I burnt about 15 movies using DeVede. I tried the movies in 4 different DVD players with only 2 working out of the 15. However, they all work on a fifth DVD player. I used DVD-R discs. The program suggests that it puts it in a format for all home DVD players to run. They are rar, mkv, mp4 and avi files. Does anyone have any knowledge to whether I might of done something wrong, need a better program or it's really just the DVD players fault for lack of compatibility?

Thanks if any has any knowledge they can lend.
