I just got my PVR350 TV-Out working as well using this guide and a lot
of poking around at posts on this list and the ivtv list, so I'll
comment below.

Yes, currently you need to create 'some' of the video devices manually
which the howto gives a nice 1-liner for.

I'm not sure if you meant to say 'cat test.mpg > /dev/video16' but
everything I've read you would see problems there because of the small
blocksize cat uses.  In this case you would want to do a 'dd if=test.mpg
of=/dev/video16 bs-64k'.  Of course if it worked with the cat, great.

Are you sure your using the correct device?  Take a look at your
/var/log/messages and look for 'iTVC15 TV out frame buffer device'.  The
device you use will preceed that statement.

The other thing that I had to do was download, build, and install the
'latest' CVS of ivtv.  For some reason I had problems with the 0.9.1
version I had installed.  I would get a screen full of garbage as soon
as I loaded the driver.  No change when I tried to send MPEG to
/dev/video16.

What version of ivtv are you using?  Anything interesting in
/var/log/messages or /var/log/XFree86.0.log? (assuming you've run the
X-server)
