Hiccups in playback on extender but not client

[wayner]

I have just set up a new SageTV for WHS server - I moved some tuners over from my previous setup on Vista HP and I bought a new, second HD-PVR. I am getting a weird playback problem but it only seems to affect Recorded or Live TV from one of my HD-PVRs - tuner 3 or HD-PVR1. The problem is that every 3-4 seconds of playback there is a slight pause or "hiccup" in playback - but this only occurs on my HD-200 extenders, not on SageClient! And this is consistent on different extenders (I have 4 of them).

This problem does not appear to be evident on files / live TV from my other HD-PVR. But if playback is fine on a client then it wouldn't be a problem with the source file/HD-PVR would it? But if that is the case why is it happening with only files from one of my two HD-PVRs?

This problem is occurring on my "old" HD-PVR that I have had for about 6 months. I haven't had problems like this before until very recently when one file played back very stutter, almost like slow motion, on my extenders but not on my SagePC. But that was just one recording - others were fine.

FYI - I have tried changing the resolution on the box connected to this HD-PVR from 108i to 720p.

I am running the 1230 firmware on my HD-200s.

Any suggestions? I will try swapping HD-PVRs so that the troublesome HD-PVR is connected to the other cable box to see if that makes any difference - this will put it back to 1080i as I believe that the other box is set for 1080i.

Anyone have any other ideas?
