Hello everybody.

I have the same 2 DVB-cards as Hermann Gausterer and additionally an 
analog Mediafocus from Technisat.
For a long time I had the same problems that he has , but never could 
find a solution on the mailing list.

So I took all my modest abilities and searched for the reason of the 
problem and for a solution.

Here is, what I found out:

The problem only occurs, after the machine was powered off for some time.
When the drivers is loaded, and I do a make rmmod in the DVB driver 
directory there happens an error:

lsmod shows the following after driver is loaded:

dvb-ttpci             301728   4
evdev                   4224   0  (unused)
input                   3584   0  [dvb-ttpci evdev]
ves1820                 4080   0
stv0299                 6752   0  (unused)
grundig_29504-491       3488   0
grundig_29504-401       3888   0
alps_tdlb7              3952   0
alps_tdmb7              3600   0
alps_bsrv2              3856   1
dvb-core               38288  27  [dvb-ttpci ves1820 stv0299 grundig_29504-491 grundig_29504-401 alps_tdlb7 alps_tdmb7 alps_bsrv2]

Then I do a "make rmmod":
/lib/modules/2.4.18-6mdk/build/scripts/pathdown.sh: TOPDIR: parameter null or not set
sync
(       \
make -C av7110 rmmod; \
make -C frontends rmmod; \
rmmod dvb-core;          \
         \
)
make[1]: Wechsel in das Verzeichnis Verzeichnis »/TV/linux-dvb.2003-06-08/driver/av7110«
rmmod dvb-ttpci; \
rmmod evdev; \
rmmod input;
dvb-ttpci: Device or resource busy
input: Device or resource busy
make[1]: *** [rmmod] Fehler 1

After that lsmod shows the following:

dvb-ttpci             301728   0
input                   3584   0  [dvb-ttpci]
alps_bsrv2              3856   1
dvb-core               38288   6  [dvb-ttpci alps_bsrv2]

Doing a second "make rmmod" removes these modules.

After that I do a "make insmod" and then the problem is solved (in my case)
I tried this now for a few times, and it allways worked for me.

I don't know the reason of the "make rmmod"-error, but in my case it seems to be the origin of the NOVA-problem.
I don't think it has to do something with the Mediafocus card.
So I'm optimistic that this can solve the problems of the other NOVA-users too.

Maybe this helps to perform the DVB driver, so that there will be a more elegant solution.

best regards
Martin

P.S. VDR is great!!! Thanks a lot to Klaus and all the other developers!
