I have tried changing the resolution and bitrate settings around, with no
improvement.
I am getting some "NVP: prebuffering pause" messages.
I tried output through PVR-350, but still have the jitter, so I am pretty
sure it is on capture.
I have read through the troubleshooting sections on ivtv and mythtv and
everything else I can find with google and haven't found anything that makes
a difference. And that includes rebuilding the machine from scratch. I am
really worried that I am going to have an expensive doorstop on my hands,
unless someone can help get me on the right track.
Any thoughts anyone?
Thanks,
Aaron
