Some Recordings Stutter & Jump

[sub]

How often is this happening, and is it just certain channels?

How often is this happening, and is it just certain channels?

Channel number doesn't seem to matter. They are all analog.

I noticed a way to trick NPVR into working though. I have to open it, go to Live TV, when channel jumps (they all do on first open) I go back to main, then re-open Live TV and it is smooth. Also after doing this, if I close Live TV and leave NPVR's main window open, my recordings don't jump.

I thought I had found the problem, but I have been able to make it better. Something over-wrote SAF 6.12 so I uninstalled ffdshow and LAV then uninstalled SAF 6.12 and reinstalled SAF 6.12. I changed all decoders to ffdshow and things were running much better in NPVR 2.3.4. I upgraded to 2.5.5 and now channels that are broadcast at 4:3 stutter and jump but those using 16:9 seem to work just fine. Weird.

EDIT...

If I close NPVR and re-open it, the 4:3 channels seem to work after going to 16:9 channels the first time NPVR is opened.

I'm not really sure what to suggest. Can you make a short recording available so I can download it and take a look?

Here ya go...

I went to C-SPAN because it is broadcast at 4:3 on DirecTV.

Plays bad here with MS decoder. This was analog out of your DirectTV box, right?

That is truely odd. I've never seen anything like it from an analog device, and I'm not really sure what to suggest. That must be what the hardware encoder is producing.

You haven't added any other PCI hardware recently that might be interfering with your HVR-1800?

I haven't upgraded anything and my computer is pretty fast with that 6-core AMD Phenom II CPU and 16 GBs of DDR3 1600 memory.

Yup

I think I fixed it! I noticed that the satellite signal had been lost on the History Channel so I had to reset the STB. After doing that, I wondered if channels I knew to be jumping before were still doing so. NONE are jumping so far! I am not sure if there is a buffer or something in DirecTV STBs, but resetting should have cleared something out. I'll post again on how it goes.

Phew - glad you found it because I had no idea.

I did say it looked like a digital device with signal problems. Unfortunately I didn't get as far as the idea of your STB having those signal problem, and your analog device capturing it.
