Ordered a Region 2 SD220 from Amazon last week, took delivery on Friday morning, plugged it in and all worked fine. Tried it on a couple of discs (Gladiator and the Mummy) with no problems. Have been away for the weekend and when I tried to view the Gladiator disc again yesterday, the picture is now jerky and 'stutters' at approximately 2-3 times a second (difficult to describe!). There's no break up in audio or the picture quality; it just doesn't run smoothly as it did. Before I send it back, anyone any ideas?
