[mythtv] Firewire channel changing

I have firewire working more than less with a SA3250HD cable box.  In
general capturing video works well.  Channel changing via firewire
works most of the time, but fails occasionally.

When I first started playing with this firewire setup, I tried live tv
for a bit.  It did not take long for the firewire port to get very
confused.  If I avoid live tv, the firewire is much more reliable.

I believe I am seeing a pattern where channel changing via firewire
works well as long as it does not need to record two shows
back-to-back.  I am starting to wonder if the channel change is
unreliable if the firewire port is already open and streaming video.

Does Myth's firewire recorder close down the port before calling the
external channel changer?  If not, I believe doing so would make the
system more reliable.

This is all conjecture, as I am still very new to this firewire stuff.
