you can test kanotix with vdr and xineliboutput in live mode. So you can check if your hardware is o.k.

> Whenever I am using vdr-sfxe or xine-ui to watch tv, switching channels

> 1) start vdr as demon (with xineliboutput)
> 2) fire up vdr-sxfe (use a local pipe or rtsp or whatever) or xine xvdr://
> 3) send a SIGKILL to the frontend process (so either vdr-sxfe or xine)
> 4) system freezes hard immediately without any logs or whatsoever
> I believe this is the same problem I have been expierencing at random. I

> Here some more informations:
> - OS: Gentoo ~amd64 (64 bit -hicks-)
> - KNC ONE DVB-C Plus with Cineview and Alphacrypt Light CAM
> - fresh (a few days old) dvb tree from mercurial repository (linuxtv.org)
> - 2.6.19rc6git10 (almost 100% identical to 2.6.19-final)
> - xinelib 1.1.3_pre20061129
> - vdr 1.4.4 with bigpatch, setup plugin, jumpplay, dvbplayer, cmdsubmenu
> dolby-record-switch, submenu and femon
> - xineliboutput 1.0.0_pre6
> - gcc 4.1.1 (gentoo rev 2, meaning there are a lot of fixes included and
> not vanilla)
> - glibc 2.5
> Naturally I also tried older kernels and older dvb checkouts but that
