First I have to say that I've used DVD decrypter to back up one of my dvds and it worked great, i was able to play it on my dvd player without any problems. Now, I tried to burn avi files on to dvd using avi2dvd, which created iso file, which i burned on to dvd by using the same method as with a back up dvd. Now, here's my problem, after dvd was finished my dvd player wouldn't recognize it. Why???? I don't understand how it would play one but not the other? Please help, I've wasted 3 dvds with the same results.
