[linux-dvb] Stability of turning filters on and off

[Dave Chapman <dave@dchapman.com>]

hi,

I'm writing an application that involves starting and stopping various 
filters on the same multiplex.  Obviously, I want this to be as reliable 
as possible with the wide range of DVB cards now supported.

My question to the driver developers (especially for the less mature 
drivers) is should I set all required filters once when first tuning to 
the multiplex, and then discard packets from /dev/dvb/adapterN/dvrN that 
I don't need.  Or is it 100% reliable to turn filters on and off from 
userspace?

i.e. if I am recording data from PID 1 and then want to add PID 2 for a 
short time, will PID 1 come through uninterrupted?

Regards,

Dave.
