It seems like the Fusion5 needs just a bit more signal than my TV does.
Once I put a cheap combined amplifier/splitter in, I can get a good
signal on all channels.  Hurray!

Even with a good signal, pid filtering still makes the difference
between a stream with annoying artifacts, and a nearly clean stream.
(mplayer complains about CRC checksums failing every few seconds,
but I can't see/hear any problems).  I sure hope myth does pid
filtering..

Also, I see tons of these message in my dmesg log, are they
anything to worry about?
