I just tried the siemens_dvb-0.9-20011117.tgz from the vdr-ftp-server. No
changes. A couple more tests showed strange behaviour:

When I start vdr with the primary card set to "2", watching tv is
fine,switching channels works.

Jan  9 19:11:53 matrix vdr[7423]: found 2 video devices
Jan  9 19:11:53 matrix vdr[7423]: setting primary DVB to 2

When a recording starts, the display freezes but the recording works (on
card 1, I suppose). When I try to switch channels I get the "can't start
Transfer Mode" error on the frozen tv image.

When I start vdr with the primary card set to "1", I get:

Jan  9 19:52:31 matrix vdr[8290]: found 2 video devices
Jan  9 19:52:31 matrix vdr[8290]: setting primary DVB to 1

but it always records on card 1, switching channels is blocked, and there
is no option in the menu, to stop the recording.

It looks like there might be a kind of ressource conflict, that keeps vdr
from talking to card 2 when card 1 is busy.

I detected, that the second card is sharing interrupts with the isdn card
and an additional ide controller:

  9:   18951340          XT-PIC  saa7146(1)
 10:   13729405          XT-PIC  ide2, HiSax, saa7146(2)

Might this cause the problem? If so, how do I change the interrupt used by
the second card?

Is there something like i/o-ports to configure? Any tests I can make to
further investigate this issue? Or should I mail this to the DVB list, to
get assistance?
