Samsung reset the ports yesterday via remote management. I think the issue is beyond a reset, but I will try the unplugging for 10 minutes

When do the 1-2 second blackouts occur? Only once following the pressing of the play button, or throughout the movie?

When watching a blu ray, the couple seconds of black usually starts shortly after the movie begins. I'd say in the first 5 minutes. If I pause the blu-ray (and shut the tv down) to briefly do something else, the Samsung will repeat the blackout, once again, in the first 5 minutes after replay. I haven't noticed any pattern while watching the tivo, other than it's only happened when i watch a recorded show. This second issue started within the last week.

Ok, thanks for the additional info. What you're describing actually may be normal behavior of the hdmi connection. Have you ever heard of an "hdmi handshake"? It's a standard protocol that's carried out between source components on an hdmi connection to establish a compatible list of settings the two components will use to communicate. A handshake will last a second or so, and when it involves a change of video resolution and/or frame rate on your tv, the video will blank. This happens all the time for me when I change a channel on my native video output FIOS DVR. Every time my 8500 receives a "change" of video resolution from a broadcasted channel from my DVR (i.e. from 720p to 1080i or vice versa), an hdmi handshake will be carried out, and the video will blank for a second or two before displaying the new channel. Your cable box (Tivo) may set its video channel output at a defined resolution (i.e. 1080i), so there would be no hdmi handshake necessary between your tv and cable box from one channel change to the next, thus no blanking screen will be seen. On your blu-ray player, I suspect when your player outputs 24Hz frame rate (typical for blu-ray movies), while your tv is presently in a 1080/60 Hz video resolution, an hdmi handshake will happen when your tv has to switch to the 24Hz frame rate. Once the tv has switched to the 24Hz frame rate (while watching your movie), no additional hdmi handshakes are needed. I would try turning off 24Hz output from your Oppo player (let Oppo player convert movie to 60Hz output), and that may stop the initial video blank upon playing your blu-ray movies because your 8500's standard/native frame rate on power up is 60Hz.

The most important thing is the VT60 are a rip off now.

However to answer the question, more or less a tie. The Panasonic does better in some area's and the Samsung does better in other area's. Seeing how the samsung's are priced, easy choice now........

DanF8500, I think it could be a handshake issue, but this tv replaced a Samsung 63c8000. I never had this momentary dip to black with the older Samsung and the same Tivo or Oppo. Also, I currently also own a 60e7000, with a tivo and Oppo hooked up to the tv. I have never had a that tv go to black while watching a blu ray or tivo, either. So, I wonder whether it's faulty ports inside the 8500. I just want to try and figure this out before I call Samsung again. My fear is that the hdmi ports inside the tv may eventually stop working altogether. I hope to figure this out before the warranty period ends. Thanks for your commens.

^ If it was a faulty port on your tv, I suspect your Tivo connection (all your connected devices) would be blanking also. The fact that it functions fine watching tv broadcasts suggests your hdmi ports are not going bad. I've seen a good number of owners complaining about 1-2 second blanking video on the Oppo forums. Almost every one of those posts was the result of hdmi handshaking.

Thinking of buying Darbee 5100,connecting it from my oppo 103 to the f8500.
Any idea if it will enhance picture quality or I won't see much difference.

I LOVED my Darbee when I had a ST60.To me the F8500 is noticeably sharper than the Panny and putting the Darbee effect on top of this sharpness looks bad to me. I haven't experimented with the Darbee set at less than what I ran before (45%) but for now I leave it off. I'll save it in case I ever get a projector.

I get the same thing sometimes and I'm pretty sure it's not handshake related as it happens to me mid-gaming session when there is no change in resolution. I just always figured it was my receiver hdmi port being wonky, but if it's happening to other users then I may need to reevaluate.

While the game doesn't change resolution mid session, frame rate can dip and rise depending on how taxed the console is being. That might cause the tv to request a new handshake. That wouldn't explain your issue during blu ray watching though.

I was thinking 103d, could you experiment a bit further for us?

I'm not sure how helpful I can be beyond the opinion I gave above.

None of my observations will be scientific... Being based upon my perception and preferences... And if I have to lower the Darbee setting below what many consider the 45% sweet spot IMO you might as well leave it off or save the money.

I DO like the Darbee. Just not with this TV. The F8500 already shows enough detail IMO and the Darbee seemed to make film grain pop more than I like. For me the Darbee effect was much more pleasing with the softer ST60.
