Yes, of course. I guess I am still a little sleepy after a nightshift ;o))

Whoops. I have never seen a rev 1.3 CI(!) board. I missed that on the first
pass across your mail. I only know of 1.4 CI (which works) and a rev 1.5
or 1.6 CI(!) board, which doesn't work. 

To add some confusion to it all, I have a rev 1.4 CI board here (connected
to my 1.6 DVB boards), which has a CiMax 2.0 chip on it and it works very
well with the LL firmware. I have recorded several PW films and never 
experienced a CAM failure during recording using the LL firmware. (haven't
gotten around to upgrading to the newest VDR & DVB drivers, tho, but the
problems where around back then, too). 

CAMS I use: Alphacrypt 1.0 & 1.10 and Magic Module with Pentacyrpt 1.09
and 1.10 (a few of the other MM firms do *not* work with the LL firmware,
but they also present problems in my Nokia 9902S)

AFAICR the rev >1.4 CI board has an even newer CiMax chip on it and
the board layout of the CI changed, too. All people I can remember
having a rev >1.4 CI board never got the LL firmware to work.

Greetz,
Reinhard
