Hi,

Attached patch fixes one doc-mistake: key for prev channel is k not l (Or 
should this be changed in source of v4l input driver ?)

It also gives the advice to use noaudio-option, if the card got an external 
audio-output.

Without nonaudio-option one gets one frame per ca. 30 seconds ...

Hopefully this is useful to someone...

Best wishes,

Fabian

PS: I write all this, because i today got a tv-card with bt878 chipset. And as 
i wanted mplayer to play it, i had to debug long to find the error / right 
option to use ...
