Zdravim. Do ruky sa mi dostala TV karta : 
00:0a.0 Multimedia controller: Philips Semiconductors SAA7133/SAA7135 Video Broadcast Decoder (rev d1)
        Subsystem: KWorld Computer Co. Ltd. Unknown device 7253
        Flags: bus master, medium devsel, latency 32, IRQ 18
        Memory at ea010000 (32-bit, non-prefetchable) [size=2K]

V /dev/ mam vytvorene : 
$ ls /dev/ | grep video
video0
Tv kartu spoznalo mythv. Aj ostatne. Ale nedari sa mi ju spustit. V mythtv zobrazi : 
 Selhalo otevreni karty
Dalo by sa to neakym programom vyskusat okrem xawtv. Ten mi tam nesiel. A distro je MythBuntu 7.10.

      pozri sa na tento návod
      pointa je, že modul by sa mal zavádzať týmto príkazom:
      modprobe saa7134 i2c_scan=1

      predtým si ho najprv odstran :
      rmmod saa7134

      a vyskušaj či ti to funguje. Ak ano na tej stranke si prečítaj ako to nastaviť na trvalo...

         mplayer tv:// -tv driver=v4l2:norm=PAL:input=0:amode=1:width=384:height=288
 :outfmt=yuy2:device=/dev/video0:chanlist=europe-west:channel=E2
        Nabehla iba cierna obrazovka.

          A skusal som aj tvtime 
          # tvtime-scanner
Reading configuration from /etc/tvtime/tvtime.xml
Scanning using TV standard PAL.

    No tuner found on input 0.  If you have a tuner, please
    select a different input using --input=<num>.

                    tuneru priradil 0 co je generic/neznamy, preto nevytvoril /dev/vbi0 ,ktory je potrebny pre ladenie, takze pravdepodobne z toho nic nebude

                      vbi0 sa mi vytvorilo :

                        potom som si vsimol ;), ale aj tak modul nepodporuje dany subsystem a preto ho registruje ako generic, skus este manulne nanutit modulu cislo tuneru, ale sanca je miziva, o tom ze vbi0 nefunguje sveci aj vypis z tvtime-scannera
