I have a HLP5063WX Samsung DLP TV and it is connected to a STR997 Sony receiver. This receiver upconverts everything to componant output to the TV. The audio and video are not in sync. The problem seems to be the worst when watching cable through a Motorola HD cable box. We have it hooked up in a 5.1 speaker configuration at this time. The room is about 15' by 15'. Thanks for any input.
