When you reload the driver, do you have to reload the firmware, or do
you set "loaded=1" so it just uses whatever is already there?



Incidentally, I've just noticed there are two sets of firmware for the
kfir... the exact one used depends on what type of stream you request:

vtv:  program
vtv1: system
vtv2: transport

The second set provides the same functionality, but is called "vtv8,
vtv18, vtv28". There is code in the driver to switch between them,
controlled by this variable "DVB_MODE". However, DVB_MODE is ALWAYS set
to 0, so only the first set is used... anyone??


Eek! just noticed the time! Bad Andrew, hacking at 2am again :)
