Why 800MB

Ok lets run cdrdao on a 700MB CD-R:

Command:
cdrdao disk-info --device 0,1,0 --driver generic-mmc-raw

OutPut:
Cdrdao version 1.1.7 - (C) Andreas Mueller 
  SCSI interface library - (C) Joerg Schilling
  Paranoia DAE library - (C) Monty

Check http://cdrdao.sourceforge.net/drives.html#dt for current driver tables.

Using libscg version 'andreas-0.5-UNIXWARE_Patch'

0,1,0: SONY DVD RW DRU-500A     Rev: 1.0f
Using driver: Generic SCSI-3/MMC (raw writing) - Version 2.0 (options 0x0000)

That data below may not reflect the real status of the inserted medium
if a simulation run was performed before. Reload the medium in this case.

CD-RW                : no
Total Capacity       : 79:57:74 (359849 blocks, 702/807 MB)
CD-R medium          : DIGITAL STORAGE TECHNOLOGY CO.,LTD
                       Long Strategy Type, e.g. Cyanine
Recording Speed      : n/a
CD-R empty           : yes

Ok now what we care about here is the

Total Capacity       : 79:57:74 (359849 blocks, 702/807 MB)

The 702/807 MB has to do with how much data the CD-R can hold in Modes 1 / 2. CVDs/VCDs/SVCDs use Mode 2 which is the second number the 807MB. So I aim for 800MB so when the CVD image is made, it will be bigger then the MPEG by its self.
