[mythtv-users] PVR-250 and weird recordings, slowing/speeding

[James L. Paul]

Aloha,

Dual PVR-250 Redhat9 box running 0.15, Athlon 1.4GHz with JFS filesystem, all 
drives DMA. Everything has been working very well for months. Nothing has 
been reconfigured since 0.15 was released. Using ivtv 0.1.9.

Has anybody seen a problem like this:

Within the past week I've suddenly begun having some recorded programs show 
timing problems. It's not a playback problem, if I move the captured file to 
another machine it shows the same effect. It's hard to describe, but the 
video and audio look fine but "skip" forward a few times a second, and 
sometimes seem to slow down. It's almost like if there was a variable speed 
control, some kid would be twisting it back and forth wildly. I've never seen 
anything like it. Many programs are fine, but 1 or 2 recordings a day are 
having the problem.

I'm not seeing any drive errors, and CPU stays below 50% even when both tuners 
are recording. I'm just not seeing any problems other than this sudden quirky 
speed problem on some recorded programs. I haven't determined yet if it's 
only one card doing it or both.

In a possibly related issue, around the same day this problem appeared, an odd 
tuner problem appeared. Sometimes a channel is "glitchy" with lots of 
horizontal flipping back and forth that I first thought was a bad VTR at the 
TV station. Reloading the ivtv driver usually cures it for a few hours. When 
I see it happen, most other channels are fine. I've never seen this before 
either, just started happening out of the blue.
