Does this Sony DVD have some new kind of protection? This DVD will play correctly on my DVD player But will not play correctly on either of my Blu-ray drives with any of several different software programs. In a crucial scene short sections of the file are replaced by a black screen. I ripped the DVD with ANYDVDHD and the VOB file where the error occurs plays correctly when played directly but when accessed through the IFO file the blacked out sections reappear. I have never seen this before.
