Hey all.
I have a CTS430 mediaroom/pvr anywhere connected to a Samsung PN50B540 plasma tv via component cable.

When pvr output is set to 720p, I experience intermittant, temporary juddering every now and again. The juddering happens every 15 or 20 minutes or so, and when it happens the picture stutters for maybe 10 or 15 seconds. If while the juddering is occuring I pause the live broadcast for a second or two and resume play, the juddering is gone.

I do not experience this issue at all with my HTPC, PS3 or dvd player at all so I think it's a pvr problem.

I have tried an HDMI cable but that didn't help. I did find that if I switch pvr output to 1080i, the juddering seems to have gone away. Although 1080i seems to cure the juddering, I do not think the video quality is as good so I'd like to rectify the 720p problem.

Are there issues with pvr buffering or something? Anyone else have this problem?

Any insights welcome.

have you tried 1080i using an HDMI cable?

Here are some other suggestions that might work.

Power cycle everything. Your router, the telus modem, your PVR, Your TV etc and plug everything back in.

Switch to ethernet (if possible) if your connected via coaxial, if not then good

Reset the telus modem and or router by pushing the tiny pin for 30s

Thanks Moiza67.

Tried all tips and no joy. Juddering is apparent in 1080i too afterall. Not sure whats going on yet.

How is your PVR connected?

I am going to assume you have the Dlink triple play router?

I am going to assume now that a phone line is attached to your router. Out of the router there are 4 ethernet slots. I am going (and correct me if I am wrong), assume the one goes to your PVR, the PS3, the HTPC and another PC.

If this is the case the juddering maybe caused by bandwidth limitations. Not by Telus, but the physical limitations of the 100mbps router. If the ps3 is accessing content from the HTPC, and or the HTPC is downloading something, or your transferring large files across your home PC network and the PVR is recording 2 HD shows while tuned to a SD station, its game over. There is only so much information you can pump through your home network with one router. Juddering happens because the PVR has to skip over data to keep the live feed live so you see the judder (a loss of packet information).

Try using the telus router for only telus TV, and use another router for everything else. See if that helps. So Use the telus routers ethernet ports to connect to your PVR and to the WLAN port of another router. Use the latter routers LAN ports to connect your other devices.

Hey Moiza

HTPC is connected wirelessly. I d/l some stuff, but not alot and the issues happen even when HTPC is powered-off.

PS3 is connected wirelessly but it is used for games only. No media content/streaming at all ever.

I have another pc connected via LAN but it never d/l's anything or uses heavy bandwidth.

I live in a new building and understand there is fiber all the way to the building incoming from Telus.

PVR and non-PVR are connected to gateway via ethernet cable. No coax.

I have a new Linksys WRT54GL (I believe that's the model number-it's in storage) and maybe I should tie that in and use it to feed both pc's and leave the D-Link for TV only?

The problem really does seem like a buffer problem of some sort because if I pause a live broadcast the instant juddering starts and press play immediately after, the judder is gone. If I leave the juddering to sort itself out, it typically lasts for anywhere from 10 to 20 seconds or so. Sounds like a buffer problem doesn't it?

Well I'm on holidays after tomorrow, so I'll dig out the Linksys router and install it during my off-time. Can't hurt to try.
