Converting .mov file to DVD-playable

I'm using a free version of video converter for converting a Quicktime .mov file into something that can be played on a DVD player (AVS Video Converter 8.3).

It works for simple .mov videos I've taken with my camera.  However, I'm receiving an error when I try to convert a more complicated file.  The error reads '‘Access violation at address 0DFB2112 in module ‘AVSQuickTimeFile3.dll’. Read of address 0000000.'.

In this file, I've pasted together multiple clips into a single .mov file (some videos, some music slideshows built in Quicktime Pro, etc)

If a 'quick fix' doesn't come to mind, perhaps you can refer another software package (freeware preferably, but not absolutely necessary) for converting .mov files to DVD-playable.

Thank you!
