I have had this problem happen to me with apollo dvd copy a couple of times, but my solution was to use dvd shrink and dvd decrypter. now i have run into this problem again and need a solution. my iso burns fine, and works perfect in my computer and in my memorex 7" portable dvd player. but in all other dvd players it says unsupported or tells you the dvd doesnt have a playback feature. how do u enable playback? by the way im converting divx/avi - 1)vso divxtodvd 2)dvd shrink 3)dvd decrypter.
