[mythtv-users] Occasional vertical pars appearing in picture

[Mike Gray]

I'm not certain if this is a MythTv issue, per se, but I'll put it out 
there anyway.

Every so often, maybe weekly, the picture in recorded shows or when 
watching live TV will have a series of vertical bars in the background.  
They're like a light reddish or maybe a pink hue.  If I reboot, the 
problem seems to go away.  But, the bars are definitely recorded into 
shows.  The picture is watchable, but very annoying.

I'm using MythTv 0.12.  Also, my capture card is a Hauppauge PVR-250.  
I'm using an IvyTV driver from maybe 2 or 3 months ago.

My first thought was that maybe its heat related.  I have an Antec 
Sonata case with 2 120mm fans running and there seems to be excellent 
ventilation in there.  I even tried putting one of those little fans 
that sits in a PCI slot directly below the card and that doesn't seem to 
help.  Also, the box is in my basement, where for the last few days it 
has been pretty cold.  I don't have any other typical heat related 
symptoms like random system crashes or the like.  When I pop the cover 
it doesn't seem unusually warm in there.

I thought maybe the capture card is bad, but it would seem like it 
wouldn't be something that pops up every week or two and goes away with 
a reboot.

Has anyone out there had a similar problem?  I'm getting pretty 
frustrated because it seems like a heat-related symptom where there 
doesn't seem to be a heat related problem.
