What's your video source and size when converting with SMC that syncs audio/video real well?

The only way I’ve done it is through another converter first.  Then SMC.  I use anydvdconverter. 

Video

codec:  xvid

Size: 320x240

bitrate: 768

Audio

Codec: mp3

bitrate: 128

And then I make sure the output is in English.
