[DVR] Choopy on demand

My on demand is choppy on either free or paid for movies. I had Verizon out today who offered to switch out my DVR. Surely it can't be the DVR though since TV is OK and that comes over Moca like On Demand, doesn't it? The tech tested the signal strength going into the DVR and it was fine. That's all she did. Where do I go from here?

Reglar channels do not come over MOCA, they are delivered in the QAM spectrum. OnDemand is delivered via IPTV / MOCA. So, I suppose theoretically it could solve the problem.

First thing to try - reboot your router. It's simple, and sometimes really does fix these types of issues (we had persistent pixellation recently, with VOD, and this fixed my problem). Second thing to check - do you have any splitters in your configuration? Are they rated to 1GHz? I had another similar issue a couple years ago.

We'd moved to a new house, and I set up all my equipment. FiOS guy came out and hooked me up. I went to watch VOD on one TV, and got major choppiness on the feed. I tried an SD feed instead. Same thing. I tried a DIFFERENT VOD title... same thing. I then tried a remote feed from my DVR to that TV. Again... same thing. The linear channels were fine, but anything that got sent through my router were not. Turned out the issue was very very stupid. My surge suppressor.

The surge suppressor I have includes a coax connection (coax from wall to suppressor, and from suppressor to STB/TV). At the old house I never bothered to use that connection - I just went from wall to STB. At the new house, for some stupid reason, I decided to use the coax connection on the suppressor. The suppressor couldn't handle the frequency needed for the MOCA feeds. I bypassed it, and voila! Problem solved. The MOCA feeds come in at a high frequency. Anything in your set-up that can't handle that frequency will cause the problem that you're seeing. Could even be faulty coax... or your wall plate being faulty. Try rebooting your router first, and then look through your setup. Anything that can help you with a process of elimination. For example - do you have another STB in your house? If so, swap that in place of your DVR and try VOD.

It's the original setup done by Verizon 4 years ago. The splitter I assume is 1Ghz. It's always worked in the past but maybe it's starting to go wrong. I'll follow your suggestions though. Thanks.

I, also, had the same problem.....Unplugged the DVR for 30 seconds and plugged it back in.....Problem solved.

(never though of re-setting the router, though.....lesson learned.)

I would definitely reboot/reset the router. If you've had it for four years without a reset..it could fix it. I've had DVR and VOd issues fixed by a reset of a router.

How long have you had the problem? I don't watch on-demand movies but my playback from my DVR to my other set top boxes has been choppy for about 2 months now. I called tech support and they talked me through resetting all the boxes and the router but no luck.

I hardly ever watch on demand so I have no idea how long it's been like that. I know the last time we ordered a movie, it was OK and then last week when we ordered one it wasn't so I really don't know. I'll try resetting the DVR and the router.

Even though the tech was there, check the tightness of ALL the coax connectors between the ONT and your STB(s).

I had an issue, a while back, where most regular channels were OK and others had pixel blocking and digital noise but only on one STB. No amount of resetting or rebooting fixed the problem. I finally checked the connectors along the coax run to that box and found that the one that connected to the F connector in the wallplate was just barely loose. I finger-tightened it and have had no problems since.

I then looked at the other two STBs' coax and found another that one other was just slightly loose but was not causing any grief.

Yep - good advice. Had the same issue with 2 HD channels a while back. They were the only 2 to pixellate, but because they were only breaking up on one TV, I knew it couldn't be the ONT. I checked the connections behind the TV - cable to splitter, and from the splitter to my DVR and my router. Sure enough, the coax connection going into the splitter was barely loose. Hand tightened it and the problem went away.

Also discovered pixellation on VOD on my main TV this morning (the only thing more annoying that Yo Gabba Gabba, is watching it while the picture keeps breaking up). It was fine last night, but not this morning. Reset the router, and the problem disappeared.

I've mentioned this before, but the reason only a few certain channels can be impacted by loose or corroded connections (or bad splitter for that matter) is because of the frequencies of the QAM channels on which they reside. It's a physics thing.

Yep, that's true. I've certainly seen that before.
