kaffeine crashes X on dvb playback

[GSMD]

Running Hardy amd64 fully up to date

$ dmesg | grep DVB
DVB: registering new adapter (Technotrend/Hauppauge WinTV DVB-S rev1.X or Fujitsu Siemens DVB-C)

Kaffeine would find channels but trying to watch any of them would freeze the machine and bring the entire Xorg down.
This is likely related to http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=469594.

I also have my xorg crashed when I try to watch tv through kaffeine. This has started now I have switched ati drivers, it worked when I used the Ubuntu Hardware Drivers utility (however more things went wrong when I switched to that) but now I switched to Envy to install the driver it doesn't.

I am running Ubuntu Hardy Heron.

This is likely one of those hundreds of fglrx bugs. Same behavior under Gentoo which I moved to.

See last comment of Bug #97341 for a solution that worked fine for me:
See also Bug #366549.

Kaffeine -> Settings ->xine Engine Parameters -> Video -> driver: change from "auto" to "xshm"

Maybe somebody can provide some technical background infos, why this works and if it is the best driver to use....
