    Place the splitter between tivo and the AVR. It needs to be the first HDMI tivo sees.

    The splitter I got doesn't strip HDCP so much as use the valid HDCP from port 1 to keep port 2 running no matter what it is connected to, so port 1 needs to be talking to a real device that is responding to HDCP in order for port 2 to work for things like a capture card, etc. I don't know if all the splitters work this way or not, but it could be a problem if they do.

    I'm lucky... mine only goes black for a half of a second about 5 seconds after I turn on the TV. I have an open ticket on the issue. TiVo only pays attention when the volume of reports goes up. I hope everyone is calling in.

    This worked for me. I have a harmony remote and there is a "power toggle" option in the TiVo command menu when setting up the remote. This is the same thing as putting the TiVo into STAND BY MODE.

    I got a refurb Bolt on Black Friday. It worked great a couple of weeks ago but has been acting up ever since the latest software update. At first I was receiving the HMDC error than just a blue screen the last few days. I called TiVo support and they had me do the usual switch imputs, disconnect and reconnect yada yada. I checked the forums here and found herbman's post. The last few days I have been using power toggle or put the TiVo into STAND BY MODE. I still get the blue screen the next day, possibly after the daily update but this works for now.

    im in the same boat. Not sure if i am glad to hear it is a software and not hardware. I bought my Bolt on BF as some of you. Worked great for a few days and now when i take it out stand by mode, my tv says searching for signal and blinks a few times for a minute and then i get picture. My 2nd time i contacted tivo i was told it was a known issue. Resolution...call mid week to see if it is still an issue, might have to swap it out. Seems that is not the resolution here. Used the cable they gave me, plugged directly into my TV. Never had an issue on my other tivo so i know it is not my tv.

    I'd like to share my experience trying to find an answer to my perplexing intermittent playback issue with my TiVo Bolt. My initial setup had the Bolt output going to my Blu-ray player (for video processing) and then sending the Blu-ray output to the TV. I used this setup for a long time and had no playback issues whatsoever. The only problem with this setup was that I was not able to see the A/V processors on-screen GUI. I finally decided to change the setup and I routed the TiVo output to the A/V processor and the A/V processor output to the TV. That's when my perplexing intermittent playback problems started.

    Sometimes, everything worked fine ("everything" = FF, FR, skip forward, skip backward and the all important "D" button). But, most of the time (when I used one of the "everything" buttons), the TV screen would go black for a second or so, and then resume playing. It looked like there was some re-handshaking going on for some odd reason. Not knowing whether or not the Bolt started having brain seizures, I put the Bolt back through the Blu-ray to the TV and lo and behold, playback had no problems. I put the Bolt back through the A/V processor and the playback problems came right back. Then I put the Bolt directly to the TV and again no playback problems. Sooo, I put the Bolt back through the A/V processor and again the intermittent problems came right back. Between all this chuck and jive, I also played with a multitude of HDMI cables to no avail.

    Even though all my devices are (supposedly) HDMI 2.0 and HDCP 2.2 compliant, I soon found out that I was probably having an HDCP issue. Since I only experienced this playback problem when the Bolt was connected through the A/V processor, I naturally assumed the problem was with the A/V processor itself. I called the A/V support line and explained what was happening. I was told I should turn OFF the HDCP function on the TiVo. I said I didn't think that that was possible. They said I should call TiVo and ask them how to do that. Well, I didn't call TiVo, but I did call some folks in the A/V business.

    What I heard through the grapevine is that with the advent of HDCP 2.2 (thank you Hollyw$$d and R$AA), new chips were needed to handle that handshake between the source and sink device. What I also heard was that "early" chips did not always handle the HDMI 2.0 and HDCP 2.2 handshake correctly. Sometimes it worked fine but, sometimes not. My A/V processor was about as early of a production run as you could get with HDCP 2.2 built in.

    Doing a bit more poking around, I found that one could possibly "fix" the inadequacy of dysfunctional HDCP chips by getting a gizmo that would "force" proper HDCP to the TV. These devices are supposedly able to do that:

    4K Up/Down Scaler
    Integral 4K60 4:4:4 600MHz : HDFury.com | Fix HDCP Error and Solve Connecting issues
    Linker 4K60 4:4:4 600MHz : HDFury.com | Fix HDCP Error and Solve Connecting issues

    I also heard that a relatively cheap fix that may work is a splitter that strips out HDCP. BUT, splitters are not sold with a label saying "strips HDCP" on them, so getting one that actually does strip HDCP may be a bit challenging:

    Tweaking4All.com - How to remove HDCP from HDMI signal ...

    I decided to try swapping out my "early" production A/V unit with a current production A/V unit. I wanted to see if the issue had been fixed in production but the manufacturer was not letting on (or possibly not telling the support desk) of a potential HDCP problem in early units. I have had a current production A/V processor running for a short while now. And, so far (knock on wood), it looks like the HDCP handshake problems are gone. All the TiVo "everything" functions work without any playback issues.

    My guess is that there may be a significant number of A/V units out there with "early" HDCP 2.2 chips that are buggy. I'm not sure TiVo can fix an intermittent HDCP handshake problem that may inherently be caused by early, buggy HDCP chips. Especially when the chips reside in the A/V unit itself and not in the TiVo. (TiVoMargret, are you listening?)

    Happy holidays and Merry Christmas to all!!

    Nope, there are no buggy HDCP chips. What there is, is a buggy HDCP standard which is hopelessly ambiguous and doesn't address how to handle any real world usage that people run into :).

    Basically the odds are somewhere around 80% that equipment from different manufacturers won't speak HDCP reliably. You should read some of the threads in the AVSForums with people trying to get HDCP problems fixed with different receivers, TVs, blu-ray players, etc.

    @clark_kent thanks, interesting devices, i have never had a HDCP issue but i do have issues that everytime i fast forward on the tivo (or other DVR) the TV and soundbar via ARC use it as excuse to re-negotiate the audio path - most times this causes a delay in the sound coming back, sometimes it breaks the sound :-( i wonder if the HDFury would help...

    @alexb I don't know if the HDFury will help or not, but I have heard that ARC can be problematic. Have you tried getting sound to the soundbar some other way?

    No as i don't want an AVR (this is a 5.1 vizio soundbar with satellites and subwoofer) and each of the HDMI devices goes directly into the TV. I guess i could figure out if the Vizio 4K TV will optical/spdif audio out to the soundbar.... I guess i should ring Vizio and ask them to sort their kit out :)

    (PS HDFury guys let me know the unit won't solve my issues, they seem very responsive by they way, i almost wanted to buy one just because of that!)

    Can you link which model? This is driving me crazy with my Bolt and my old Viewsonic N4200w. The premiere was always fine over HDMI.

    Just want to add that I have been experiencing the same HDMI issue in this thread on a Bolt and Panasonic Plasma. Before December of 2016 it had been working perfectly for a year.

    The SOWTECH Splitter mentioned above solved the issue!! (placed splitter between the tivo and AV reciever)

    I hope TIVO fixes this.

    Thanks bmdoss!

    Since the 20.6.3.RC13 release I've not gotten the "HDMI connection not permitted" error at all. Has anyone else noticed any changes over the last few releases?

    Samsung UN65KS8500 and Bolt+, still get HDMI connection not permitted at times when I begin playing a new recording. Seems to happen when the tivo changes resolution, like from 720p to 1080i. I'm on software version RC15. Still some work to do with HDMI handshake. I use a direct HDMI connection between the Tivo and the TV, using the cable supplied with the Bolt+.

    I've got an 8000 Samsung from last year and a Bolt, and basically every time I either switch inputs to the Tivo, or change shows where it's changing resolutions, the picture appears, then after a few seconds blanks out a few times, then the connection works.

    It's semi-annoying, but doesn't sound 1/10th as bad as what some are seeing? But I guess it's a variant on the same issue?

    Does TiVo not like...use their own hardware anymore?
