[linux-dvb] Re: popen for ac3 and thread (ringbuffer) problem

["Robert Schneider" <Robert.Schneider@de.ibm.com>]

I can confirm that behaviour. I first thought this is something that comes 
with the newest drivers but it's true, I can reproduce that reliably.

Andreas,

could you provide the little diff with your change so that I can check 
whether the problem gets cured at my end?

Regards,

Robert

Can anybody else confirm this behaviour?

I like the idea that the AC3 decoder ist started only when an actual
replay is performed, and not running all the time, so I would like
to be very certain about the necessity of this change.
