[mythtvnz] Pixellation Every ~ 20 minutes

> Some more tests:
>
> 1) Fresh install of mythbuntu 12.04 (I recorded the Wimbledon Final on
> July 9th without pixellation - so something has happened since that
> time, I think) -pixellation problem occurred.
>
> 2) Back on Arch, I just watched half an hour of TV3 using VLC to open
> the capture device. Pixellation at the 20 minute mark as per mythtv.
> So - it's not something to do with Arch/MythTV (at least not
> directly). A check of system monitor during this period showed CPU
> usage actually fell, presumably as there was less info being presented
> for processing.
>
> So: a lack of frames / info being presented by the card - but only
> under linux (not in Windows or to the TV tuner). Occuring every 20
> minutes or so. Mine wasn't resolved by attenuating the signal (3-20dB
> range) - although I could try again, I suppose to see if I can
> replicate Pauls' findings.
>
> Hopefully the USB DTV-B tuner will arrive tomorrow to test.
