Same issues here with Conax 4.00 and VDR >= 1.3.32. In general, the
recent changes have seemed to introduce a lot of different CAM problems.
Still, those changes are clearly important.

Same here. The CAMs I have just stop. They appear in the CICAM menu, but
don't appear to be working normally. When I change to an encrypted
channel ( for example:
Discovery;Telenor:322000:C0M128:C:6875:900:901=eng:301:B00:40:0:7:0) the
picture is shown for a while and after that couple of seconds (pretty
much same as the length before picture freezes when you shut down VDR)
it freezes. Changing channels back and forth repeats the issue. This
happens in transfer mode (my primary card doesn't have a CAM). After
resetting the CAMs everything is normal for a couple of hours or so
(impossible to say). Also I've noticed that if I keep on watching the
channel the problem doesn't appear on the, let's say, active CAM.

This behaviour naturally causes VDR to exit with "no usable data
seen..." when a timer starts on an encypted channel.

1 x Fujitsu-Siemens DVB-C 2.1 (primary)
2 x TechnoTrend DVB-C 2.1 wth CI and Conax CAM 4.00e
Fedora Core 4, VDR 1.3.36 at the moment
