<div>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).
<div>I'll try changing the PCI slot and move it further away from the graphics card.</div>

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