My HTPC and Denon 2312 AVR seem to have HDMI handoff/handshack/whatever issues. The HTPC is connected via HDMI to the AVR. Then HDMI to a Mitts HC 4000 PJ.
Upon switching to the HTPC the AVR switches fine, however when I go full screen with an AVI file the screen goes blank/blue for about 5 seconds and then the video feed returns and we can watch the video when the video is over and I minimize the video the same sequence takes place. All the while the sound is coming through the AVRr to the 5.1 speakers.

Other info that may apply
This problem didn't happen with my Denon 1910. I recently upgraded to the 2312.
The geforce video card is about two years old in the HTPC. I would have to open the case to find the model number of the card.
I have swapped out hdmi cables to no avail

Thank you in advance for your thoughts!

I have the same issue, I think because I have my display driver set to 60 Hz refresh rate, and XBMC set to synch the refresh rate with the video rate - so when it switches from XBMC dashboard (60 fps) to the movie (24 fps), it switches the video driver into 24 fps mode, and the signal chain takes some nice to resynch I guess? There's a setting in XBMC where you can tell it to delay when switching modes, so I added like a 7 second delay, fixes the issue - although you have to wait, which is kind of annoying. I may try switching the video card refresh rate to 24 Hz to see how that works.

PROBLEM SOLVED!

The video card setting was on auto detect and I changed it to full screen. That has stopped all video drops. I checked about a dozen movies and all played on various players and even in XBMC without any issues.

For those wondering what setting I'm referring to please see the pic below. I circled in red the setting I changed to fix my issues.
