I am having problems converting avi to mpg (mpeg1) for vcd. Tempgenc is making wonderful quality vcd's BUT, there is no sound at all. For some reason even files that i have previously converted with no problems will not now convert the audio. I have tried the help in virtual dub to no avail, i have looked at using nandub too and it didn't work.

Any help or suggestions would be greatly appreciated as i'm at my wits end with this one
