I haven't spotted a v4l device yet, but perhaps there is.  What you do seem
to get though is a whole series of scripts which will easily tune to any
channel for you, and there are also some devices from which you can read
audio and video directly (havent yet looked into the details of the
devices).  The tuning scripts are less than a few kb each, so I doubt there
is anything too profound going on, but I have only had this thing for a few
hours and I'm still setting up rather than coding.

For a really basic step one integration the tuning could perhaps be done by
using the same scriptable mechanism as the IR channel changing stuff for an
external box (I think?).  Some of the other DVB TV programs seem to support
something similar already, ie you maintain an external list of interesting
channels and their parameters and then you can call tune with the channel
name (as text, eg "BBC-1") - so just make sure this matches the mythtv
channel callsign for each channel.

After than you can pipe the device directly to mplayer to play the mpeg
stream (although there seems to be a need to pipe it through something to
change mpeg type from ts (transport stream) to ps).

Can someone give me an overview on how the PVR250 works for comparison? I'm
guessing that myth tunes a v4l interface, reads out the picture data from
that interface, stuffs it into a non v4l PVR250 device, and read the mpeg
output from /dev/video?  Is the output of /dev/video something that you can
push directly into mplayer?

Thanks
