I have recently taken delivery of a demo Sony 10 HT and initially was a little disappointed. AV Sales kindly lent me a PJ for a demo but didn't have a screen at that point so the picture was projected onto a greenish wall. That evening during viewing every time the camera panned or moved there were clearly diagonal lines on various parts of the picture but as soon as the motion slowed or stopped the pic was fine. Unfortunately DVD or PS2 is my only option of source material(due to S Video constraint's) 2 days later AV Sales kindly had a screen delivered so I could set it up as I had originally planned, screen in the bay window and PJ on back wall. Now the viewing from this position was much better and after viewing Hannibal I hadn't seen any lines, problem solved, but then when going through my collection the diagonal lines re-appeared. Now admittedly they weren't as bad but at the moment my mrs is jumping on any reason not to have the projector so if anybody has a 10 HT and hasn't any of these problems please post a reply, the more ammunition the better. P.S In general the picture is beautiful and most certainly involves you more in the film than a CRT tubed Tv does. I LIVE IN HOPE !!!!!!!!
