does anybody here know of a good free dvd/avi burning program, and also a veryy simple one that would work on my vista?
ImgBurn is a very good burning program.
If you want a program to convert avi to dvd video format, I’d suggest DVDFlick or FAVC. Of those two I prefer FAVC for avi to dvd conversion. http://favcfavc.googlepages.com/
Once converted, you burn to disk with ImgBurn.
Look through the guides at imgburn.com forum on using the program.
