Hi, I tried a few DVD programs with Win 7 32 bit, some don't seem to work, or 'hang' somewhere during compilation.
I have had good results with
Imgburn, and have read many times about good results from other users, so it's not just me.
The DVD burner I have used since XP days is
Trueburner from Glorylogic, never lets me down, but it's not always possible to find it on the net, but it's free and well worth a try, if you can find it. (Is also called
Burnaware), see;

A new one that promises to work with Win 7 is at;

Would say that if you keep wasting DVD's on these programs, it might be worth looking at trying a different DVD drive, just possible it's playing up somewhere. I have 2 'built-in' DVD drives (Sony & NEC) and an external Samsung, and they all can give different results with different DVD brands.
Also I always use a x4 burn speed as that improves the chances of it actually playing back.
