Analogtv Plugin help wanted

Hi

I'm trying to let vdr work with a Hauppauge pvr350 board using analogtv
PLUGIN. I followed the instructions in the README files, installed the
ivtv drivers, loaded the modules, patched vdr ......
I did all this operation with vdr 1.2.6 and vdr 1.3.12, in bith cases I
cannot see anithing displayed on the tv attached to pvr 350 output.
If i try cat /dev/video0 > nonsense.mpg and then try to play it I see a
film with the standard noise from a tv tuner with no antenna attached.

I Have no DVB card inserted
I am using a kernel 2.4.23
I dont load any DVB modules, only ivtv modules
I Have done no change on the vdr /video/setup.conf file
I haven't created any device in the /dev directory
In the same system I had before a dvb-s board and vdr was finely working

with vdr 1.3.12 in /var/log/messages I got
