Quando eu executo o tvtime, ele me fornece a seguinte saída no terminal:
Running tvtime 1.0.2.
Reading configuration from /etc/tvtime/tvtime.xml
Reading configuration from /home/md/.tvtime/tvtime.xml
xvoutput: No XVIDEO port found which supports YUY2 images.
*** tvtime requires hardware YUY2 overlay support from your video card
*** driver. If you are using an older NVIDIA card (TNT2), then
*** this capability is only available with their binary drivers.
*** For some ATI cards, this feature may be found in the experimental
*** GATOS drivers: http://gatos.souceforge.net/
*** If unsure, please check with your distribution to see if your
*** X driver supports hardware overlay surfaces.
Também tenho a placa-mãe intel 845gvsr e meu sintonizador de TV funcionou em edições anteriores do Ubuntu com essa opção options saa7134 card=3 tuner=69 colocando dentro do arquivo /etc/modprobe.d/options .
