I posted the quote below about a week or so ago. I went through several setting on my receiver (Marantz PS5003) as well as my PS3 and DirecTV DVR. I think that I am experiencing handshake issues - maybe normal or maybe not. The ~5 second delay when changing channels or sources I can deal with. However, on occasion I will lose the picture all together when changing sources or resolution. Typically, turning my receiver off and back on fixes it. It is not replicable either. For instance, one time I finished watching a movie on the PS3 and when I hit "exit" to get to the PS3 menu the screen flickered and never came back - I only got the "no source" message. However, when we watched a movie a couple of nights ago I was able to exit the movie to the PS3 menu without much of a flicker at all.
The thing is, I can't say for sure if it is the projector or the receiver that is causing these issues. Or if it is just the combination of the components that I am using. I can't say for sure that there even is a problem. If this is normal and just the nature of the beast I can live with it. However, if there is something more going on here I would like to get to the bottom of it. Is it common to have these handshake issues with the HC4000? Any other ideas? Or should I give Mitsubishi a call?

Whenever I change channels on my DirecTV HDVR or especially when I switch input sources I get quite a bit of flickering and momentary loss of HDMI signal. For example, if I change channels, it may very briefly show the new channel, then go to the blue screen/no signal screen for a few seconds, then maybe show a picture for a second, back to the blue screen for a couple seconds and then finally back to the picture. There have been a couple of times where it couldn't lock on and once where I had to turn everything off and back on. On the other hand, I occasionally change channels and it immediately goes to the new channel.
Is this pretty typical with an all HDMI/projector setup or does it sound like I could have an issue somewhere? Is there any chance that all the flickering and the losing and regaining of the lock on the signal could cause damage to shorten the life of the projector?
