[linux-dvb] Re: DVB-s Card - no picture

[Nico <nsabbi@tiscali.it>]

As clearly stated in mplayer's docs, the shutdown happens
because the current dvb code needs  the card always on, so you need to 
load dvb-core
with dvb_shutdown_timeout=0 (which disables PM). You can do this adding

options dvb-core dvb_shutdown_timeout=0

in /etc/modules.conf

If you want to remove this requisite and enable the PM you can apply a 
patch
that I posted recently to mplayer-dvb@mplayerhq.hu.

I can watch a program for some seconds. I do not really know, what causes that, because when I installed the modules I could use mplayer dvb:// without any problems. Now, after reboot, it does not work any longer.

But mplayer needs them for compiling with dvb support. Do you know if I can find the ost/include in the debian dvb-driver-source.
