[linux-dvb] Problems with DVB-S + DVB-T system

[Seppo Ingalsuo <seppo.ingalsuo@iki.fi>]

Hi,

I have problems to set up vdr streaming server with TT-Budget2 DVB-T and 
DVB-S cards. VDR crashes with streamdev plugin activated. Without the 
plugin vdr refuses to switch channels to the non-primary device. I use 
fresh CVS DVB drivers (I tried also about one month old version) with 
Linux 2.4.22.

I think the problem is in DVB drivers because I'm not able to 
simultaneously activate (after tzap and szap commands) dvbstreams piped 
to mplayers. One dvbstream at a time works without problems.

I have moved the DVB cards to slots which do not share IRQs but it 
didn't help. /proc/interrupts shows:

The motherboard is ASUS K7M with Athlon 950 MHz CPU. Here is DVB related 
dmesg output:

The tda1004x.mc file (v2.15a) is in /etc/dvb. Do you have any ideas what 
could be wrong?
