Okay, so your issues are a little more significant than what the rest of us have seen. In general, the "known" problem is:

- There are two HDMI resynchs with the 875/905 set to 1080p - one between the source and the Onkyo, and one with the Onkyo and the TV. This generally was taking 5-8 seconds when set to 1080p

- When set to through, it was generally taking 3-5 seconds, not much longer than when connected directly to the TV

- With the latest firmware updates, the resynch is much faster, and now takes no more than 3-6 seconds for all combinations, which is better, but not perfect.

- I don't think anyone has seen that error you mention

I still don't understand why, when set to 1080p, the Onkyo should ever cause a resynch with the TV. Of course it will need to resynch with source devices, but it should never drop the HDMI/HDCP connection with the TV if it's upconverting everything to 1080p. IMO.

Anyway, I hope you get this fixed!

Yes, I've been using "Auto" setting as well for the HDMI output. However, during tests I had tried forcing to "1080P" and "Through" to see if there was any difference. All modes have the same loss of signal result when changing source resolutions. Even the 875's OSD causes the loss of signal to my TV as a result of the OSD being at 480i resolution.

Bob from Onkyo tech support believes it's a signal strength issue with the hookup to my Samsung TV. However, if the HDMI board in my TV is replaced and it still does the same thing, I may be stuck. I don't know if attempting to replace the 875 will correct the problem. Bob seems to think that it will not.

It would suck if it turns out that the Samsung 61A750A DLP is simply incompatible with this receiver. Maybe that's what you get when you buy something that's just released.

Separately, does anyone get the sporadic static burst, on all speakers, when listening to cable programing that contains Dolby Digital 5.1?

Hopefully I'll learn more tomorrow, when the Samsung tech arrives to take a look at the TV.

I can't find anything about the audio sampling rate capabilities of the 875 either in the manual or in this thread. Does anyone out there have the answer?

Bob, at Onkyo tech support, seemed to squarely redirect this as problem with the TV's ability to hold on to the signal properly. I could very well be stuck here with this problem. I again wonder if the as yet to be announced 876 might work-around this issue. I'd hate to keep this unit, only to find out that this was addressed in the upcoming model.

I would suggest changing the HDMI cable between the TV and 875 just to be sure it doesn't have a construction problem or internal damage that can't be seen from outside. This is a long shot, but you never know. I'd suggest using one of the newer HDMI cables that are certified for HDMI 1.3a (may be called Category 2 or something like that). These newer cables are wider bandwidth and tend to have lower internal signal loss. Also, if you are using a longer cable length, you could try a shorter cable since long cables tend to increase signal losses.

This may not make you feel any better, but I'm evaluating a Samsung plasma right now... a brand new model that has been shipping for about a month. When I change inputs (sources) or change resolutions it goes though a noticeably longer period without picture or sound than any other TV that has been here recently. The Samsung also throws up "searching for signals" messages on a black screen at the drop of a hat. Recent Sony, Pioneer, and Panasonic models never do anything like that and lock onto signals faster without an messages about losing signals or searching for signals. I never timed any of this and just wrote the Samsung as being quirkier by nature. It's not bad enough to really bother me, though I have to say, seeing that "Searching for Signals" message so often does get annoying after a while.

I am using an 875 with 1.04 firmware with these displays. I also use an HDMI distribution amp (1 input, 4 outputs) with the 875 being the 1 input. The Samsung display is the ONLY display connected to this device that has ever caused me to have to do a power reset to get the HDMI distribution amp working right again. This tends to happen when I've been turning the Samsung on and off to enter or leave the service menu. But I've done the same thing a lot with other video displays and none of them have ever crashed the HDMI video distribution amp.

I don't see this as a deal-breaker for the Samsung displays... these new ones are otherwise pretty decent. I see it as more of a quirk than anything else.

You're right, it is just an annoying quirk. But I've timed how long it takes before the image reappears when changing to a channel that has a different resolution and it's 11-seconds. And this occurs not only when going from HD to SD and back, but from 1080i HD to 720P HD and back. If you're switching back and forth between two channels that have a different resolution, it really is disruptive.

However, the 875 isn't completely without fault, because it is definitely stepping on the signal strength of the HDMI. When using an SR705, on the same setup, there is NO problem. Apparently the 875's post-processing (even in "Through" mode) is attenuating the signal just enough to cause the temporary signal loss to the TV. Maybe Samsung will come up with a fix for their marginal HDMI implementation, but I wouldn't hold my breath.

Since Onkyo uses the same Silicon Image HDMI chipset for all its AVRs, your experience with the 705 suggests that you have a marginal HDMI chipset in the 875, and that, combined with the Samsung, may be the culprit. I sure hope that the Samsung tech has a good HDMI board with him - good luck!

That is interesting. I would have thought that it was the Reon processing that was attenuating the signal. But even in "through" mode the problem still occurs. Perhaps it is in the SI HDMI chipset of this particular 875.

If the same HDMI implementation is used on the 705, and that unit worked on the same setup, maybe there is an issue with this particular 875. It's difficult to track down when you can't fully isolate the cause of the problem... is it one device or the other or a combination thereof?

So I plan on finally getting a bluray player. I have narrowed my choices to a PS3 or a Panasonic BD30. My situation is this:

I had my TV profesionally calibrated. Since the settings on the 875 are global. I had the HDMI input on the TV that the 875 is using calibrated for dvds and cable. I had HDMI2 on the TV calibrated for a bluray player. So I plan on connecting the bluray player directly to the Tv via hdmi and optical from the bluray to the 875.

Being that I am connecting via optical to the 875, which player would you guys recommend? I searched alot of threads but most of the the audio talk around the 2 players revolve around an HDMI hook up, not optical.

One more question, would I be better off just going hdmi to the rcvr and live with the calibration I got for that?

Thanks in advance.

Not sure what he could be calibrating differently for the BD versus HD DVR's though.
