Sony BDP-S570. The blu-ray player is on auto and I never had issues with my previous LCD TV. That is what makes me lean towards the Panny being the issue. However, not having this issue with HD cable makes me think it's the blu-ray player. Very odd, indeed. I am hooking up a separate blu-ray player tonight (PS3) to the TV. If the issue is still there, I think I'll swap the TV for another--might just be a lemon.
