New to MediaCoder - DVD question

[penn]

Hi, I'm new to MediaCoder and straight away I would like to say that it looks like a great program. I have a had a fiddle around but just wondered if someone could give me some pointers on settings to use for converting from a music DVD to MPEG4 with MP3 audio. I tried it on one music track from a DVD and it worked but when I tried it on another I had sound and no picture. Thanks in advance. Penn
