Does anyone have this 2 disc R1 set. I have just watched it and on CH9 disc 1 the picture breaks up, the sound stutters and the player locks up or skips to ch 12. I bought it ages ago and forget about it but a friend watched it when I bought it and reckoned it was OK. Any ideas? Anyone got the same problem. I have a Sony 7700 and a Sony 536. Hope someone out there can help, slightly distressed its the first time i've had a problem with a disc!
