Quicktime video conversion software/help with Corel VideoStudio?

Hi,

I've got a bunch of +/- 1gb Quicktime (mov/mp4) files on my computer that I would like to burn to dvd to watch on a dvd player hooked up to a tv. I tried using a free conversion program called DVD Flick but several dvd's I've burned with it had audio/visual sync problems, even when I don't do anything on the computer while the program is running.

What are some of the best paid/free video converter softwares? There are just so many that it's hard to tell what's good and what's not.

I also have Corel VideoStudio 12 that came with my computer and tried to convert with it but it crashes. I started the conversion and it seemed to work ok but my computer ended up going to sleep. When I woke it the program was at 45% and seemed to keep going just fine but I hit 'esc' to end the program because I figured I would just wait and start over in an orderly fashion and I didn't know if the computer going to sleep would have messed anything up.

So I set my computer to not sleep and started the conversion again. This time the program crashes after not very long by giving me an error message saying the program has quit. I restarted the computer and tried again, same problem. This is the error message details, any suggestions on what to do?

Thanks a bunch for any help.
