Very strange problems with my Lifeview FlyDVB-T Carbus card

Hello

I own a Lifeview FlyDVB-T Duo Cardbus TV card and have found a very strange
and confusing problem trying to use it in Linux and could do with some help.

The card has Analog TV, Digital TV and Composite inputs. I'm trying to make
the composite inputs work so I can plug some old games consoles into my PC.
I'm not that bothered about watching actual broadcast TV through the card at
the moment.

From some Googling, I worked out I needed to load the SAA7134 driver with a
card type of 55, and also the saa7134-alsa module for some sound.

Under Kernel 2.6.16 this randomly works. I've used both tvtime and mplayer and
the result is the same. Here's what happens:

I own a Super Nintendo and a Playstation. They both have composite output with
the standard Red/Yellow/White plugs.

If I plug (say) my SNES into the card, stick a game in the slot (Super Mario
World for example) and then launch tvtime all seems to go well. I can pick
the 'composite2' input and then turn on my console.

However, from then on I can only get an image if I unplug the yellow video
lead from the card and then tap it on the middle pole of the card's yellow
connector. Every time I interrupt the video signal this way, I get one still
image. Completely unplugging the video gives me uninterrupted sound until I
reconnect the video when everything stops again.

The really strange part is that if I plug my Playstation in instead it works
fine! Until I load certain games, when it stops working again (or it can get
to a part of a game and the images will stop). To my limited knowledge, it
seems that the consoles aren't sending out the correct signals or are
attempting to change "resolution" to display different things. The card is
set to use PAL, and both consoles are PAL devices that by default give a
standard 50Hz picture. When I do see images they are the correct size, shape
and colour. They're not deformed or appearing half way down the video window.

Naturally, both consoles work fine when connected to a TV, and this convoluted
setup works in Windows.

Has anyone got any ideas why this is happening?

I've attached the output from lspci, the kernel modules loading and a running
instance of mplayer.

My machine is a P4 3.2GHz HT laptop running Gentoo Linux and kernel:

Linux hex 2.6.16-gentoo-r1 #1 SMP PREEMPT Fri Mar 31 01:17:35 GMT 2006 i686
Mobile Intel(R) Pentium(R) 4 CPU 3.20GHz GenuineIntel GNU/Linux

The mplayer commandline I'm using is this:

mplayer tv:// -tv
driver=v4l2:device=/dev/video0:chanlist=europe-west:alsa:adevice=hw.1,0:amode=1:
audiorate=32000:forceaudio:volume=100:immediatemode=0:norm=PAL:input=2

(imagine this is one large line without the linebreaks)

Thanks
