Knoppix didn't want to start (couldn't read the CD, not sure why, maybe 
too old), but I found a Ubuntu 7.04 live/install CD. Started with that, 
no difference. I did find something else: I've got three different 
lenghts CI cables. One approx. 60cm, a few others approx. 40cm and some 
approx. 4cm. With 60cm, both the offical Mediaguard CAM and Xcam won't 
initialize. With 40cm, the Xcam still won't and the Mediaguard will init 
about 50% of the time. With 4cm, both Xcam and Mediaguard will always 
init. But it still doesn't work properly, even with the 4cm cable I 
couldn't get a picture with the Mediaguard, and I had a picture for 
about half a minute with the Xcam after which Kaffeine would freeze.

I'm not sure if it's a driver problem, all I know is that this started 
right after installing a new v4l-dvb a few weeks ago. The problem seems 
to have no cause:

Not the DVB-card, as the S2-3200 had the same problem.
Not the CI cable, tried many different cables and I don't believe they 
are all broken the same way.
Not the CI-daughterboard, I even bought new ones with no result.
Not the current v4l-dvb loaded, because a Ubuntu 7.04 live CD (kernel 
2.6.20 iirc) has the same result now.
Not the computer, because the setup didn't work in another computer either.
Not the CAM, all CAMs work fine in a Vantage standalone.

And note I have used this setup, S-1500+CI+long cable+Xcam for months 
without any problems.

I'm baffled.
