Hi Kyle,

I was having frequent issues recording from WFXT in PS mode, probably
the same as you (though I'm using an HD2000 with DVB drivers).  It was
characterized by "No data from card in 1 second" messages for the
duration of the recording.  I switched to using TS mode a couple of
weeks ago and have had no problems since.

I had tried changing the PMT timeout in dbvchannel.cpp from 3 seconds to
15, but that didn't help.  If Taylor's statement that it's due to
missing PID 1FFB is correct (my backend logs seem to support that), then
it's not suprising.

Sounds interesting, but I think I read that the PS mode for recordings
from DVB is likely to be removed, so it might not be worth spending too
much time on it.

  Steve.
