[mythtv-users] Trying to use HDTV as a firewire recorder

I have a Samsung HDTV with both a cable card and IEEE1394 ports.  For 
the past several months I have been able to use test-mpeg2 and "at" to 
record shows.  Of course, this has many limitations.

I have set-up my TV as an "OTHER" firewire box.  I created a "channel 
changer" program that will power-up the TV (IR blaster), set the input 
to "TV", tune to the appropriate channel, and "prime" the firewire using 
test-mpeg2.  The problem is that the backend appears to be recording, 
but the file is always 0 bytes.

I have tried all 3 speeds (100M, 200M, and 400M) and a few different 
cable box models without any luck.  I would appreciate some help getting 
this to work.  I can provide output from logs files, plugreport, etc if
