Re: [Encode2mpeg-users] DVP642 A/V sync problem with ac3 5.1 audio

[Robert F. <rob...@gm...>]

Try it using tovid to encode and see what happens.  Tovid uses enc2mpeg as
default for encoding, but there is a -ffmpeg switch.  Using 'Gutsy' my .avi
have been encoding well with  tovid (but not in 'Feisty')
