I made complete "Clone DVD" copies using AnyDVD 6155 and Clone 2908. Pans Labrynth: copied disc - but when I re-inserted the disc in the computer the drive seized up and the computer had to be restarted. When I inserted into my panasonic DVD player the disc worked but there was no audio despite trying all audio options on menu. Letters From Iwo Jima: appears to play fine in computer but seized up in my panasonic DVD player - had to unplug then eject movie on power-up. I have recently started cloning the full disc instead of copying the main movie with titles. I don't know if this is the cause of the problem or if something is wrong with the above software version. Also, I tested both my computer drive and DVD player with other commercial and earlier AnyDVD/CloneDVD recordings and have experienced no problems.
