Meanwhile I managed to use LIRC and an IR transmitter diode to send
channel switch commands to my Digibox, so all would be ready for a
complete integration of an external analog video source into the VDR
system - if only the driver wouldn't mess up the second and every
following TS recording...

Is there really nobody here on this list who could at least try the
above tests, so I would know if this is really a driver issue or maybe
I'm doing something wrong? I've been looking at the kfir.c code over
and over again, but I can't seem to find anything that could be changed
to fix this :-(
