I will compile this version and see if it works.

Is there a difference between 2.6.1 and 2.6.2-rc1/2? I load the firmware
through the hotplug firmware interface. I found out if i boot first 
2.6.1 and then into 2.6.2-rc1/2 the video output works in 2.6.2-rc1/2 
too. So i think it is really a firmware loading issue. But i wasn't able 
to solve this.

Here are the kernel messages from both kernel versions:

2.6.1 output:

Looks identical to me. The loaded modules are:

ves1x93                 8784  1
dvb_ttpci              82064  5
dvb_core               60052  34 ves1x93,dvb_ttpci

video_buf              19012  1 saa7146_vv
saa7146                17576  2 dvb_ttpci,saa7146_vv
v4l1_compat            14852  1 saa7146_vv
v4l2_common             6912  1 saa7146_vv
videodev                9664  2 saa7146_vv
firmware_class          8832  1 dvb_ttpci
ttpci_eeprom            4288  1 dvb_ttpci

And another totally unrelated question: is it possible with the revision 
1.3 card to get ac3 output?
