I have two dvd's of Pink Floyd's The Wall. One bought in South Africa (Limited edition: 50198 6) and one bought in London (501989). I use a superb Samsung DVD player with NO hassle at all. My problrm is that BOTH dvd's freeze on charpter 18 (approx 1:02 time) with the dead soldiers in the trench on exactly the same spot. The visual freezes and the audio is broken up. Has anyone had this problem?? It is totally inexplicable to me!! Two dvd's with exactly the same problem ... almost impossible!?! I cannot enjoy either version's chapter 19 till the end. HELP!
