This is just a temporary hack that lets one switch between playing the left or the right stereo channel (by pressing 'S'). It cannot detect bilingual broadcasts.
This is the first attempt at adding proper support for bilingual programs to mythtv. It is limited to ivtv.
This version stores the language that was last selected for a channel or a program. There's a version for mythtv 0.14 and one for mythtv 0.15.
It still lacks an easy way of enabling the recording of both languages
for ivtv cards, that still has to be done manually (test_ioctl -z 1)
Replace manual configuration, via test_ioctl, by a new setting on mythtv MPEG2 profile screen.
Complete rewrite to take advantage of new MythTV audio track selection. It does not save the language on the database anymore.
