[linux-dvb] Re: Questions about new API

Ralph,

Thanks for your clarification (and for to Marcus and Johannes for their 
replies) - the logic makes sense now.

If I set a video and audio pid for a channel as you've all described, then I 
can nicely read the data from /dev/ost/dvr.

However, if I try to do something else - e.g. mixing video and audio pids for 
different channels, or just setting the audio pid (i.e. a radio station), 
then things go wrong.  i.e. I am getting perfect audio and (if set) video on 
my TV, but /dev/ost/dvr never provides me with any audio information.

Have you experienced similar problems?  I'm using quite an old driver (0.8.2 
with the "n-tv patch" applied) and am testing on the Astra 28E satellite.  

I guess it's time for me to upgrade to a 2.4 kernel...

Thanks,

Dave.
