OK, when i load tvtime as tvtime --device=/dev/video1

I get the an error.

Videoinput: Driver refuses to set norm: Invalid argument

When i load tvtime as /dev/video0

I get a picture, but it's interlaced with a lot of static

Then when i try to cat /dev/video0 i get a Device or resource busy

cat /dev/video1, no errors . I play the file, and i get static, barley 
see picture, i can hear audio though.

Uploaded the video file to: (only 14MB) http://systemoverload.net/test.mpg

When  i set it up in mythtv i set it up as an analogue card.

Setting it to /dev/video1 gives me these errors in mythbackend.log.

Setting it to /dev/video0 gives me the errors posted in my last email.
