tvtime not working

when i try to run tvtime i get this:
root@ajmal-desktop:~# tvtime
Running tvtime 1.0.2.
Reading configuration from /etc/tvtime/tvtime.xml
Reading configuration from /home/ajmal/.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.

everytime i install ubuntu(11.04 or older) i have to make my tv tuner card get detected by doing this
sudo rmmod saa7134_alsa
sudo rmmod saa7134
sudo modprobe saa7134 card=3 tuner=69
sudo gedit /etc/modprobe.d/options
Then append this line to the end.
options saa7134 card=3 tuner=69 then reboot to save the settings.

 kindly help my specs are:
ubuntu natty(11.04) ,756 mb ram,intel 845gvsr motherboard with no extra graphics card(inbuilt sound and graphics) support.
tvtime closes abruptly and shows above messages also there is some lack in pc performance which is other issue iam facing,i really want solution to the above problem,my motherboard doesnt support unity iam using tradition aka gnome 2 desktop.
