[Kwintv] [BUG] saa7134

[Dominik Karall]

hi,

I found this nice tv program over the net, but it does not work on with my 
saa7134 chip. It only works in overlay mode, but not correct, only one 
picture after clicking or moving the window. in all other modes I get this 
message:
"Videodisplay isn't possible" (translated from german)

Here is the lspci output for saa7134:

in this mode I only get one picture every time I do something with the window.
let me know if you need more debug information, I'm using version 0.8.1-1 from 
debian unstable.

please cc me, as I'm not subscribed to the list, thx!
