[mythtvnz] PVR-150 corruption

Mon Apr 13 06:36:25 BST 2009

Is the picture better when the Backend is cold and the fan is running slower?

I am working on a bad picture problem with analogue cards that gets worse as the CPU fan speeds up. Took me ages to realise what was causing the problem I don't yet have a way to fix it.

Subject: [mythtvnz] PVR-150 corruption

Hey all - I'm still having video corruption from my PVR-150 cards.

I was kinda hoping the 0.21 upgrade and a matching kernel upgrade would 
have fixed it.

I've saved some stills and they're at
http://criggie.dyndns.org/pictures/?gallery=pvr150

Here's an exported video showing the problem - 1.5 MB
http://criggie.dyndns.org/mythtv/TV1-second.avi

It occurs on TV1,C4, maoriTV, and DWTV/CTV  and occasionally on other 
channels.  I have a UHF aerial on the roof, which comes down to a 
splitter then into both cards.

I have tried the aerial and all leads straight into a TV and there is no 
visible corruption.

I have also recorded from a video tape into the composite input on one 
of my PVR150s and it DOES show the same corruption.

So - whats wrong... is it the cards or mythtv or ivtv or something about 
the box ?
