Hello guys

I have a Pioneer PDP-5070HD and a Denon AVR1610 and I just got a new HTPC running XBMC which I like to leave on all the time and at random times when I turn off my Denon AVR1610 and then turn it back on hours later I have no signal from the HTPC at all. And even unplugging and replugging in the HDMI cable does not fix it. The only way to get a picture and sound back is to to a hard reset to the HTPC.
My HTPC has a AMD Radeon 6320 video card which also does True HD and DTS HD.
Could someone here point me to the correct EDID file that I would need and also how to install it?
I actually ordered a HDMI Detective Plus yesterday which I understand should fix my issue with losing the signal however then I remembered seeing this thread and was hoping it could save me the $85 that I just spent. I canceled the order for now just in case you guys can fix the issue for me

The HTPC HDMI is plugged into the Denon and the Denon HDMI is plugged into the Pioneer.
It is just driving me nuts when I turn on my Denon and Pioneer and there is no signal coming form the HTPC

Also If leave XBMC running with a video playing and turn off my Denon 1610. When I turn my Denon back on XBMC crashes to my desktop and I have to restart XBMC.
Also if I use the option "Use full screen rather then true full screen" in XBMC when I turn my Denon back on the video is running but really really slow!
Hope you guys can help

Thanks
