Is this an Xvid-only problem?

Can't help but notice several different postings regarding downloads, indicating the same problem - video okay but, even with .AC3 codec installed, no .AC3 audio playback.

Perhaps the Xvid author(s) would be good enough to address and clarify this...

I personally think it is a issue on the person's (that cant play the XviD movie) computer. I have some of the movies which the people speak of that "dont have .ac3 audio", however i hear it just fine.
