hi, i have tried all available 8* and 9* version of the ati-drivers i could find together with kernel 2.6.30/31. Any other driver works fine for dvbt, so it seems to be fglrx-specific... Every version seems to have the same problem: Everything seems to work, but watching dvb-t via kaffeine results in 2-3 seconds video (in weird colors), and then just seems to kill my X-Session bringing me back to the login screen. here is what dmesg says: #-- fglrx: module license 'Proprietary.

Expected Results: dvbt-streaming should work
small update: after searching the net, i found somewhere a suggestion to change the video-output in xine to xshm. This worked and now watching dvbt with kaffeine doesn't crash X anymore. But still it seems this is an error in the ati-drivers.
This happened to me with the old versions of fglrx + <xorg-server-1.6, too. With fglrx 10.* + xorg-server 1.7 i have never seen this problem again.
