I asume that you have the DVB (TDT in Spain) working and you can watch some
channels, right? If not, tell me before following this steps.

Finally I got my Svideo an Composite inputs working this way:

   1. You should check that your inputs are working, try to connect a
   video/DVD/etc... and watch it with tvtime (you can install it from repos on
   most distros). Remember that you might no hear anything with tvtime, it's ok
   2. stop mythbackend
   3. run mythtv-setup
   4. add a new capture card (yes! another one!)
   5. select v4l capture card, you should use /dev/video0 for video and
   /dev/dsp1 for audio
   6. create a new video source (I called it VOID) with no listings (dont
   remember exactly the option, but there's one that doesnt retreive info from
   7. assing this video source (VOID) to the new input connections that
   should have appeared (svideo and composite)
   8. go to channel editor and create a new channel (mine is 1111) only
   for that video source (VOID)
   9. go to the capture card page and set this channel (1111) as the
   default channel for the new v4l card.
   10. exit mythtv-setup
   11. start mythbackend
   12. start mythfrontend
   13. go to watch tv
   14. press "Y" (changes capture card) until you get to the newly
   created, if you have your video running you should see the picture.

It's a little bit tricky but I tested it yesterday and it worked but it's
not ok:

   - Image quality is very (very) poor
   - Some times video stops for a while.
   - Sound is terrible
   - sometimes when I exit from watch tv while viewing those inputs, ALL
   the system freezes and I have to reset the box :''''(

hope this helps...

(PS: una mica estrany que parlem en anglès, no)
