convert to AC3

The Q is - why would you want to do this? TMPGEnc can't decode AC3. SVCD can't have AC3 audio. What you want is to take the audio from the AVI and decode/convert to WAV for use with TMPGEnc. This can be done with VirtualDub.

Extract the ac3 with virtualdub in direct stream copy and then get besweet to convert it to mp2.Dont need tmpgenc to encode the audio,mux it back to the m2v with either bbmeg or tmpgenc mpeg tools.

so its compleatly posible to get the affect of ac3 audio quality with svcd? and im sorry but im kinda new to this so im trying to learn as quick as i can. So to do this im not exactly how to start... with virtual dub how do i save or extract the ac3 for starters? ill look for a guid in the mean time. thanx
