After about 2 weeks with my P65, I've decided its still a keeper. And that is after not having watched anything in DV since last weekend.
Regarding my FIOS picture, I'm not sure if I've tweaked the settings properly, I've adjusted to the bigger screen, or I've been watching different shows but I am now very happy with how it looks. I just re-setup the old Sony 40" XBR3 in the basement and watching 1080p netflix via a Ruku3, my reactions were: 1)wow, this thing is small 2)It doesn't look as smooth as I remember 3) wow, this thing is dim and the blacks are awful
I am down to one intermittent issue that sounds like the video stuttering some are reporting with PC based sources. I've noticed it mostly via FIOS at 1080i and a few times on Netflix. But the majority of my viewing has been via FIOS so that may be why I've noticed it there the most.
It can't be the the HDMI cable since a) I'm using the same HDMI cable as with my old TV b) its happening via Netflix which is internal. Note that I am currently AVR-less so all sources are connected directly to the TV. I'll have to check some of the recorded shows on the TiVo to see if the stuttering happens there as well.
