I've been trying to burn some of my AVI files to DVd.  I've tried Cucusoft, Nero, ConvertX2Dvd and many other programs to convert to DVd.  It all seems to burn fine but when I try to play the DVD on my DVD players, it doesnt work.  The Dvd just keeps spinning.  As a matter of fact some of them wont even play on my computer either.  The weird thing about this is that I've burned these files before with Cucusoft and they played.  All of a sudden it just stopped working. I've tried filed that I've been able to burn before. I've tried both +R and -R.  I can burn music fine. Same Dvds from the same package that I used before reinstalling windows...........oh yeah! The only thing that has changed is that I reinstalled Windows on my computer.  From that point forward the problem started.  I've spent about a week trying to figure this out and I have finally hit a dead end.

Can anyone help.  What am I doing wrong?
