My son just bought a Sony DVD player, DVP-NS330. He got a couple of DVDs from HMV - The Firm, Only Fools and Horses - and they played just fine. So today he buys Catch Me If You Can at HMV, pops it in the slot and sits back to watch the movie. He should be so lucky! The DVD plays for a few seconds, switches back to the TV channel, then back again, and so forth every few seconds. He takes the DVD back and exchanges it for Identity. Same result. He tries his other DVDs (Firm, Fools/Horses). They still play fine. By now he's tearing his hair out and frantically phoning me. Has anybody here any idea what's going on and how to fix it?
