Ok i just downloaded a movie, and sound wouldn't work, so i loaded up GSpot and it was AC3 192kb/s. So i said ok, i knew that i had AC3 codec zipped, so i unzipped it, and it was DivX3.11 setup, and i did it. Sound still wouldn't work. Then i tried to find ac3 codec somewhere else, but they were all like that with DivX3.11 is this suppose to be like that?

So anyways sound still doesn't work, opening in
PowerDVD - no sound
MS Movie Maker - "some of the streams in this movie are in an unsupported format"
MS Media Player - same thing

any help?

PS: some people were saying that PowerDVD has full ac3 support, and i have PowerDVD 4 XP.
