    I have no idea. I can say that when it changes channels, there's at least a second or two of blank screen before it changes, except when it doesn't in which case the default "scene" from LG comes on and it can't find the signal.

    Have you checked to see if there is a software update for your TV ? My Samsung has updated about 4 or 5 times since I bought it a year ago.
    Same thing for your AVR.

    In Resolutions in the C61k, make sure the 480 resolutions are not checked. I have seen them slow channel changes down.

    That's what I was looking for. I'll bet, if you take that 61K out of the system and replace it with the 54, you will see the problem disappear. That should be easy to do, replacement is a good tool when troubleshooting. You don't have to make this permanent, just do it and see if it works correctly. If the problem disappears you should be giving the C61K a good look, that will be the answer.

    Assuming that the C61K is the issue (which has been my assumption all along), do I have any recourse or am I stuck until the next equipment refresh? Do you think this is just a bad C61K or would swapping it out make a difference?

    720p is the lowest resolution available on the C61K. I keep up with all the updates on my TV.

    The c61k handshake is different than any other unit from DIRECTV because of the fact it’s checking for hdmi2.0 and hdcp 2.2 for 4k. So swapping it really isnt going to tell you if that’s the issue by itself. It’s better to start by bypassing the avr in this case.

    Rad my last post. It’s a totally different handshake than any other unit because it’s testing for a different hdmi and hdcp version than everything else. And your avr could absolutely be causing this issue because of this difference.

    Sadly You must bypass the avr to do any real trouble shooting in this particular instance. Swapping it for the hr54 won’t tell you anything in this case.

    Another thing that you could try is to turn native off in the video settings. Lock it on 720 or 1080 and see if that helps.

    I'd bet on that assumption. When troubleshooting the first question to ask is "What Changed?", you seem to have found the answer. You can get a swap or wait for the next NR...or, I'm totally wrong about the 61...personally, I'd be getting a replacement for the 61. What do you have to lose? Calling D* and getting someone that can actually fix your problem is problematic at best.

    Tell me how the AVR can cause the problem to occur on a recording in such a way that it can be produced at the same spot in the recording over and over. What he's seeing is a problem with the recording itself, how does the AVR cause that? If his 61 is working properly why doesn't every 61 cause this problem...or do they? I don't have one and can't tell.

    So I tried removing the AVR from the equation over the weekend and still getting that multi-second delay (I never actually lost sync, but still had the same delay, and it almost lost sync a couple of times). I also tried new cables that were rated for the new HDMI specs and that didn't help. Next I will try bypassing the C61K and use the DirecTV app on my TV (which will introduce a new issue, setting up my Remote to work right and ARC issues that I've been having with this TV), but that can at least tell me if the C61K is the issue.

    Do you have any streaming devices? That LG you have has NF and Amazon apps, do you see the same problems if you use them? I think the most important thing you can do is switch the 54 and the 61, see if that clears up the problem.

    I have Roku, Amazon fire-sick, a streaming BluRay device, and my AVR can stream music. NONE of these items have syncing issues.

    Okay, that answers my question. Think it might be a bad C61? You've eliminated everything else. I'd still like to see the 54 sitting in exactly the same spot as the 61 with the same cabling. If the 54 works correctly...

    Going through this now with my HS17 minus the failures. My equipment said it’s running great but it’s not.

    If this not syncing right and having delays, that’s not a recording issue. It’s an issue getting it to work right in the first place, or I misunderstood his issue. I did not take this to be one program only at one exact spot only.

    Yes that’s what I would do next as well. It’s a process of elimination on where the connectivity issue is.

    I finally found the "bugger". The drives I had gotten Seagate 5TB Barracuda's just couldn't handle the random write workloads. Apparently, they use a special way of writing and use tiered cache to hide write deficiencies. Really, really, really kicking myself.

    What I have observed is the inbound record has zero issues with recording 4 concurrent NFL HD based games, when it moves from 5 -> 7 it does hiccup but it is minor. The recorder does get a little bit sluggish but it doesn't drop.

    How I figured it out was by popping the top and plugging the 2.5" drive in with the inbound sata cables. Then I observed the madness, and at least I feel good knowing the Oyen Digital raid was actually masking an I/O performance issue.

    So now the fun of cloning the XFS partitions over to an 8TB WD Red drive I pulled from one of my RAID arrays .... All for the love of saving the recordings that are on it so "I don't get in trouble" when she gets back from her horse shows ....

    I do think you need a mini client to get 4k...

    I'm having similar issues. Sometimes the screen is totally black after changing but I still get audio. I usually hit previous channel then back again and it works. On occasion I do have to shut off then restart. Glad I stumbled on this topic. I thought maybe it was my Samsung tv.

    That's exactly my symptom. You do need the mini for 4K. I'm tempted, at this point to forego the 4K if I can get a more stable setup and just move the HR54 to my family room and and the C61K to the bedroom which doesn't have 4K.
