[mythtv-users] mtd DVDPerfectThread read failed and wrong audiochannel being ripped

[mikef at zerompg.com]

Thanks, -aid 128 selected the correct audio channel. Now i just gotta find
out why the rip fails at the very end. There isnt some sort of data area a
few dvd readers cant access is there? I'll try a new dvd tonight and see
how it goes.
