I used to be able to make a backup of my DVD's and it would work on any DVD player in the house. After a patch a few months ago, the backups only work on one DVD player in the house...and I have several others. It says "invalid media" in all but one DVD player in the house. Nothing has changed for me at all...same media used, same burner, same everything. I usually use AnyDVD, DVD Shrink, then DVD Decrypter to burn. I have even tried using Clone DVD and that doesnt rememdy the situation at all. Any advice?
