What is ac3?
LAMA section here we go )

I have a movie that has 5 channel sound according to vdub file info.
is that it?
Anyway vdub doesnt save the waw for me, what next? ( I'm converting from ntsc to pal so I need to separate the sound )

ac3 is an audio compression used on dvds, and some vcd/svcd variations.

go to this site to learn about ac-3

www.dolby.com/company/is.ot.0011.TechOverview.03.html#s3c

if you want to keep the sound as it is - just tell virtualdub to make
a direct strem copy and save it as whatever name you want.

if you are looking to convert it to wav, then you will need a program called
"haeadac-3ch".
but befor you use "haeadac-3ch". you need another progam to check if
the ac-3 file doesnt have errors in it, the program you will need is
"ac-3 fix"
if you need something else - post a reply.
