Whenever I convert a xvid/divx file to a dvd the audio always plays faster than the movies does. And it't not like 1 or 2 seconds its a lot more. How do I fix this problem?

Try use VSO ConvertXToDVD. It has certain capacity to deal with this common sync. problem.

Is there any other way I can fix the problem? Because the audio is fine when its in AVI format.

Yes, it sounds like what you have is a 24 fps video being encoded to 29.97, when this happens it causes a loss of sync from the video to the audio, which worsens over time. If you encode the video and audio as 2 seperate files, then then mux them together it should fix that.

How do I encode video and audio as seperate files? How do I mux them together?

I am using a video capture card that creates a .mpg file of my home video and using ShowBiz DVD to convert .mpg files to DVD format. My mpg file plays fine on the computer with sound but when I convert to DVD I get no sound out of the DVD player. Why is that?

I've tried a number of mpeg encoders but always had the best luck with TMPEG. If your software gives the option (as any dvd compliant encoder should) you should have the option of selecting ES or Elementary Stream when encoding the video. This would give you the option of seperating the audio from the video during encoding, and probably give you an M2v and Mp2 file (mpeg 2 video and mpeg layer 2 audio file) or M2v and WAV file. Once this is done, check the length of both the audio file and the movie file, if the length is the same then you should be good to go. Your dvd author program SHOULD give you the option of setting a seperate audio and video file instead of forcing a MUltipleXed (muxed) file. Once you set the audio file as your audio source and the video file as your video source, do a test burn onto an RW disc, and that should have the sync fixed. Hope that answered your question without going too much into it.
