Searched w/ no success. I do a lot of DVD Shrinking. Part of the process is to remove unused audio tracks. One has puzzled me though. AC3 5.1 and AC3 2-channel. I have always deleted the 2-channel version because I assume that 99% of the DVD players or amps will all downconvert to either AC3 2-channel or PCM via the RCA output jacks. Am I right on this or are there situations/hardware where my backup DVD’s will have no audio (or messed up AC3)?
Simpler: If I strip out the AC3 2-channel track and only leave the 5.1 track when would I run into audio problems???
