Thanks mate - I will try this. It's interesting that it might be a temperature problem, as I am also experiencing a similar type of drift with my graphics card. After a few hours use, the TV-out (Svideo) loses sync and the pictures starts to roll. I can fix it by changing to a text console and then back again to X windows (with MythTV).
I'll try changing the PCI slot and move it further away from the graphics card.
cheers,
Mark

This can be a temperature problem. The first generation of the tuners on
this card has an enormous power consumption. How old is the driver you are
using?
In the last months, i changed the driver to:
- put unused components to standby mode
- make the dvb-t channel decoder more tolerant to xtal frequency offsets.
so can you please get a recent driver from www.linuxtv.org and retry?
If you have a recent driver can you try to ensure that there is some
air flow around the card (i.e. by freeing the PCI slots close to it)?
Best regards
