Hi, I have a nagging problem with my setup, i knew from the start compatibility can sometimes be an issue so i decided from the off to buy all Sony, i have: Sony Bravia KDL-46V4000 TV HD up to 1080p Sony STR-DG820 amp And a Sony PS3 used as a games console and Blu-Ray player. I also have 7.1 KEF surround sound, the egg type speakers. Connections wise, i have a HDMI cable coming out of the PS3 and into the BD port or sometimes the DVD port on the DG820, then a HDMI cable from the OUT to the HDMI port on the TV, no other connecting cables. the problem is i will be watching a movie when the TV will go black and then HDMI 1 will appear then followed underneath by 1080p then the picture comes back, almost like its switched ports on the TV, this had nearly always happened and last night we was watching ELF, the movie was in a low def format, i was watching it over an ethernet link using my PC as a media server, but this problem happens even if i watch a standard def movie. I have tried swapping ports on the TV to HDMI 2, still same, and also changing cables. do you think this could be an upscaling problem? im pretty sure i still get this problem even if i watch a 1080p movie, last night the switching happened 15+ times during 'Elf' and the family were not impressed, ive tried changing some settings around but to be honest im a bit out of my depth and hope you kind people can throw a bit of light on it. Thanks Lee.
