Writing the Lead-In and the Lead-Out is carried out autonomously by the CD burner , i.e. the CD burner program has no control over it. For many CD burners there is also no possibility to check how far the CD burner has got with writing the Lead-In or the Lead-Out. This is why there is nothing showing in the progress bar display.

Numerous CD burner can not handle burning in DAO mode. You can check this in CD-Recorder->Choose CD-Recorder to be checked. For the following CD burners this can be corrected by a firmware update:

HP 7100, Philips CDD3610, Mitsumi 4801

DAO Mode can not be handled by the following CD burner :

Acer CRW1420, Hightech CD-R2006, Kodak 2600, Kodak 2801 IDE, Mitsumi CR2600TE, Mitsumi CR2800TE, CR2801TE, Olympus CDS630E, Sony CDU926S, Sony CDU928E

Both the following burners can handle DAO mode but Nero does not support this mode for these burners: Mitsumi CD-2200CS, Mitsumi CR-2201CS.

You can find information on this in Can Nero be used to copy GD-ROMs?

The current Nero versions can not yet handle copying DVDs.

Yes and no.

There are two different types of karaoke CDs:

1. Karaoke CDs in Video CD format. A CD of this kind only contains video clips. CDs of this kind can be copied with Nero . A few CD burner however can not write such CDs.
2. Karaoke CDs in CD+G format. Read the information on this in CD+G in the glossary. CDs with this format can not be copied with the current Nero version. Only a few (high quality) CD burner are even able to write CDs of this kind (correctly).

In short: Yes

Since Nero 4.0.5.0 Nero can burn the audio files which are present in MP3 fomat onto an audio CD. In this case the MP3 files can be handled in exactly the same way as the WAV files. Nero automatically converts these files.

The answer to be brief is: No.

GD-ROM CDs can not be copied or written with normal CD burners.

• as a GD-ROM can contain more information than a CD-R/RW (90 minutes instaed of 112+4 minutes). There are special writable CD-Rs; these however are only sold to official DreamCast developers and are not available to the general public. And anyway, a GD burner would be necessary.
• The statement that the first DreamCast games could be copied may be correct but this was only possible because these games did not yet use the outer area with the high write density yet.
• You can also forget the idea of writing DreamCast CDs on DVD-R/RWs as the DreamCast console can not read off of DVD-R/RWs.

In brief: No

Reason: The Photo CD format is a standard defined by the Eastman Kodak Company to save and read picture files. The format has been kept quite simple and could be created quite easily. The licence fees that would have to be paid so that Nero can create CDs of this kind would significantly increase of Nero . This is why the creation of CDs of this kind is not suported.

To a certain extent. If the CD has only been written on once, then the CD can be copied. If, however, further pictures have been added to the Photo CD , then this CD is now a multisession CD which can not be copied by the current Nero version.

Nero can copy Video CDs. However this is not possible with all CD burners, e.g. not with the JVC XR-W2040.

In brief: No

The current Nero version can not convert audio files which exist in VQF-format which means an audio CD is created which can be played on the audio CD player.

No. CD burner, which are connected to the computer via the network can not be used for burning.

Nero can burn images of type ISO.

In the current Nero version the parameters of the ISO file still have to be entered.

• Type of image: Data Mode 1 (assuming that it is a Mode 1 image)
• Block size: 2048 Bytes (corresponds to the sector size of a Mode 1 image)
• File precursor and length of the image trailer: 0 Bytes (assuming that the image file only contains ISO data and not other special information has been entered)
• no Scrambled (i.e. it is not an image which was especially created for old Philips CD burner )and no Swapped (assuming that the files contaisn the Bytes in the correct order.

The settings are based on the assumption that it is a normal ISO Mode 1 image file. This can be checked by opening the file with a Hex Editor. For File-Offset 08000hex (corresponds to Block 16 where the ISO ([p]rimary [v]olume [d]descriptor is saved). If there is a text there like "CD001", then burning with the above mentioned method should work.

To copy CDs you are best to use the following settings.

1. Do not carry out direct copy but burn via image. Depending on the quantity of data you may need up to 800 MB of free memory on the harddisk.
2. Use the CD burner as a reading deivce as many reading options are only CD burner can be supported (Exception: see right at the bottom)
3. Some CDs are oversized. Either you use 80 minute blanks or you activate the overburn option. Unfortunately there are burners which do not support either. Further down there are a few answers on this.
4. Read speed: Depending on the quality of the CD burner or the read speed should be set accoridng to how clean the CD is. It is safest in general to read with 1x. Depending on the quality of th burner and the flawlessness of the blank, a higher read speed can be selected.
5. Read options:
• max. number of unsuccessful read trys: 3 In the case of scratched CDS or low quality CD burners the number should be increased.
• Read Media catalog number and ISRC Reading (slower) activated. But not every drive can read this information.
• Illegal TOC-type activated (if possible)
• In data track: For read errors, activate continue copy . For Mode 1 and Mode 2 respectively Read raw data if possible and set data write uncorrected .
• In audio track: Read audio data with sub channel and ignore read error set (providing the latter option is available). The option use audio correction in contrast should not be activated (or not until Nero Version 4.0.5.6).
6. The CD burner should be able to burn in DAO mode.
7. The write speed used depends on the quality of the CD burner and the blank used. For safety's sake burn at 1x. However bear in mind that some blanks made for copying at 4x, 6x or even higher speeds may possibly no longer be suitable for burning at 1x and can cause problems when sriting and sometime not until reading the written CD.
8. How long it takes to copy a CD with intentional errors dpends on the read drive used. Numerous drives give up relatively quickly and others don't. For CDs with intentional errors drives are better which give up relatively quickly and continue. Some (often high quality) drives in comparison are unsuitable for copying CDs of this kind because it can take hours until any progress is made at all (due to the burner internal correction attempts). In a very few cases it makes more sense to use the CD-ROM drive as the read device.

This case occurs if a burner recongises that the burn speed set is not possible on the blank inserted. Some burners turn the speed down, some even turn it up (!) (from 1x to 2x). As the majority of CD burner do not check the permissble speed while simulation but not until the actual burning process it is possible that the write speed changes between simulation and burning.

Nero asks before every burning process what the maximum speed is that a burner can write at (not what the minimum speed is).

There are several causes to this problem.

• your CD burner can not burn in DAO mode. You can check this, by in CD-Recorder->Choose CD-Recorder .
• You burn an audio CD and at least one audio-track originates from a CD. Then the DAO mode is deactivated unless you are burning on the image recorder.
• You are burning a CD in a certain format which your CD burner can not burn in DAO mode. Many CD burner can not handle burning Mixed Mode CDs in DAO mode.

The CD burner can burn on CD-RWs at 4x. During the burning dialog however only 2x is

4x CD-RW burners have only popular since the beginning of 1999. Many CD-RWs can only be written with a max. of 2x. Nero asks the CD burner at what speed the blank can be written on. If 2x is now returned, then as a general rule it is due to one of the following:

• a blank is inserted which can be recorded with a max. of 2x. These are in particular the CD-RWs which only comply with the Orange Book Part III v1.0. Only CD-RWs subsequent to the v2.0 standard can be written at 4x.
• some CD burner can not write on some 4x-CD-RWs at 4x but only at 2x. For example the blanks supplied withe the Traxdata 4424 Plus (make Ritek) can only be written at 2x, even though they are sold as being 4x capable.
• the blank which was last inserted could only be written at 2x. This message can also appear if there isn't a blank inserted anymore.
• the CD-RW was inserted at an unsuitable time. Some CD burner give wrong values if the speed query is carried out while the CD is logging in.

A description of how CDs of this kind can be created is in the Help of Nero .

Comment: So that Nero can create CDs of this kind, a SCSI harddisk with an HFS Partition (<600MB) is necessary, as although Nero can burn the Macintosh file system HFS, it doesn't understand it.

Nero can at the moement not yet shared Hybrid CDs burn, i.e. it is not possible to use Nero to burn a CD this way so that the files which can be seen in the HFS area of the CD can also be read from in the Iso area of the CD. Unless you burn the files double onto the CD.
