Just a followup. I got it working, had to install 2.6.18 kernel headers 
so MPlayer could compile PVR support against the new V4L2 API.

Here's the recording profile I'm using .. if anyone wants to correct any 
errors that'd be great:

[ivtv]
tv=normid=10:device=/dev/video0:width=720:height=480
pvr=abitrate=192:vbitrate=2200000:vpeak=2600000:fmt=dvd:aspect=1
of=mpeg=1
mpegopts=format=dvd
ovc=copy=1
ofps=30000/1001
oac=copy=1

@devs, I found a few bugs, too:

- Not setting width and/or height will cause the card to hang.  I get a 
syslog message saying "Oct 19 19:25:26 charlie cx25840 0-0044: 640x65535 
is not a valid size!"
- If I don't set "aspect=1", it won't set the aspect ratio.  Not that I 
can tell anyway, midentify says "ID_VIDEO_ASPECT=0.0000" on all of them, 
but dvdauthor won't complain if I do set it.
- It looks like I can't use PVR support and TV support at the same time, 
one or the other.  Running mplayer tv:// on my normal PCI TV tuner card 
just exits quietly.

There was some other stuff, but I think it was mostly IVTV hanging, and 
not mencoder.

Running SVN versions of MPlayer and IVTV on 2.6.18.1 kernel on Gentoo 
Linux, amd64.
