[mythtv-users] Green glitches + artifacts in recordings on noisy channel

[Thomas Börkel]

HI!

I have a PVR-250 rev2 and I am using ivtv 0.1.9 and Myth 0.14.

Every now and then, recordings on one noisy channel get glitchy after a 
while in the recording (after 10 in one recording and after 60 minutes 
in another recording).

Then I see green glitches and blocky artifacts and the picture is a bit 
corrupted in part. Mythfrontend complains while playing:

Is this a known problem? Is there a way around this? Chris, should this 
be fixed in one of your patches?

It only happened on that channel, so far and in 2 recordings out of 5. 
The other recordings on that channel and on all other channels were OK.

Any help would be greatly appreciated.

Thanks!

Thomas
