[mythtv] bttv or v4l?

[IvanK.]

Guys,

is mythtv hardwired to use bttv or will any v4l compliant device suffice?

The reason I'm asking is because my MSI Geforce4 ti4600 has a video-in/tv-out 
connector.  There's a project, called RivaTV (http://rivatv.sourceforge.net/) 
that provides a v4l device for NVidia based video-in cards.  I tried it on 
Monday and I could use xawtv to watch tv.

In light of this, I'd like to remove my WinTV card and use mythtv with my 
video card.  Will that be possible with the current codebase?

Thanks,
IvanK.

ps: is it of any consequence that the video card doesn't have a tuner (of 
course)?  I wasn't using the one on my WinTV either, as my cable provider 
uses a decoder cable box which does the channel switching.
