Our original Sky+ box was installed back in 2001, and had run perfectly well until January of this year. A couple of recordings failed, and didn't give the disk space back. The problem seemed to be sorted when we did a full system reset. But it came back again 2 times, and subsequently an engineer was called. He came on saturday, and simply replaced the box with a brand new one. It's a Pace box, like the old one. When the engineer left, I had a look round the services menu to add my favourite channels etc. I noticed when looking at picture settings that the video output was in RGB mode. Our first box had always been in PAL mode. What's the difference between the two? I ask because when playing back recordings, the picture tends to jump slightly on quite a number of occations. It does the same when you watch a programme again from the sky+ planner. All my recordings so far have been done with the video output in RGB. I have now put it back to PAL, to see if it makes any difference. Any help would be great, thanks.
