Just a quick note, I'm also having problems with the 1080P8. Hooked up via HDMI to my Samsung 650 61" DLP, when on the dvd source I lose the signal (completely black screen) at least once a minute, for about 5 seconds at a time.
The HDMI cable works fine when used with my PS3, same tv, same input.
The dvd player works fine with regular AV cables, but the picture suffers drastically of course.
I've purchased $40+ cables, a new HDMI cable and a sete of component cables and a digital audio cable... all for a $79 dvd player. I've yet to try the new HDMI but I'm hoping that at the very least that it works with the component cables and the picture is great.
If anyone has similar problems and possible solutions, please post.
