VSO ConvertX to DVD is freezing my computer (WinAVi did too)

I used WinAVI a few times and had trouble with the movies skipping on playback (they would play fine for about 10 minutes then start stuttering and not stop). Then, after that happening to 3 movies, I would go to convert the AVI to DVD and it would work about halfway and then freeze the computer or restart the computer.

So I googled some fixes and found that other people had that problem and switched to VSO, so I did that. VSO now freezes as soon as I click "convert"

I don't know what to do, I'm hoping someone here can help me. I don't know offhand what information or logfiles you need, but if you tell me what to do I can do it.

I ran CCleaner, AdAware, and Spybot (in that order) and the only things they found were cookies but I did delete them.
