[vdr] Only black screen with VDR, Hauppauge PVR-250 and analogTV-plugin 0.9.14 ?

Good morning folks,

yesterday I got my Hauppauge PVR 250 and plugged it into my VDR. After some
struggles with kernelversions, module dependencies and stuff I finally
managed to load the module(s) without (visible) hiccups:

player:~# modprobe -v ivtv
/sbin/insmod /lib/modules/2.4.22/kernel/drivers/i2c/i2c-core.o
Using /lib/modules/2.4.22/kernel/drivers/i2c/i2c-core.o

/sbin/insmod /lib/modules/2.4.22/kernel/drivers/media/video/ivtv.o
Using /lib/modules/2.4.22/kernel/drivers/media/video/ivtv.o

No (obvious) errors so far, SYSLOG tells me:

What does that "Device or minor 0 not accepted" mean ?
I load the DVB modules prior to the ivtv stuff so the PVR device should be
/dev/video2 (I have 2 DVB-C cards)
The Syslog output looks quite ok to me... But when I zap to any analogue
channel, VDR "hangs" for a few seconds, stating:

Although I don't understand the "switching to channel 0 on device 0" and
then "switching to channel 0 on device 4" the finally selected channel seems
to be the one I zapped to (channel 159, SAT.1). As one can see I even get
the EPG for that channel (looks like magic to me...? ) 

But unfortunately the VDR screen stays pitch black.

If I do a "cat /dev/video2 > /tmp/blafasel.mpg", then "file" tells me:

	/tmp/blafasel.mpg: MPEG system stream data

so I suspect the device itself is working. If I look at that file using
mplayer I can see at least some "snow" like one gets on TV when no channel
is tuned in.

Some additional background information:
	VDR		1.2.1
	analogTV	0.9.14
	PVR driver	CVS-LATEST as of November, 12th
	DVB cards	2x Siemens DVB-C
	PVR card	Hauppauge PVR-250

Now my question is: What am I doing wrong, what did I miss ? How do I have
to configure the analogTV plugin ? Do I have to pass additional commandline
parameters to VDR ?

Any help would be highly appreciated.
