None that wouldn’t read back, but one that wouldn’t play back in my Panasonic DMP-BD30.
16 Blocks, Aeon Flux, American Psycho, Jay and Silent Bob Strike Back, Saw, Saw II, Saw III, Speed, Swordfish, and Terminator 2, all BD-25 movies to begin with - will work when ripped/backed up to the hard drive with AnyDVD HD, built using the BDMV and certificate folders in IMGburn, and then the resulting image being burned in IMGBurn. But I tried several times with Rocky and it simply. Will. Not. Load.
