i have a similar problem but it is related to the ca module not getting 
setup or reset properly.
every single time i restart my backend computer i have to do the following:
open mythfrontend and make sure it is tuned to a channel that always 
transmitts, no picture shows up, then pull out ca module and reinsert, 
wait a little while and picture comes up just fine and everything works 
perfectly until next reboot.

has been like this for years

so perhaps the person that had the problem also have a ca module that 
gets stuck.
if i tune to a channel that don't always transmit it tends to get stuck 
semi randomly and i will get zero length recordings.

a simple ca reset at the right spot is almost guaranteed to fix it, was 
experimenting with just this a long time ago but never figured out where 
to put it in the mythtv code and how to wire up the reset.
