You might have a look into xine's stream info.

I know this issue for almost a year now, when I started coding on my plugin 
without DVB receiving equipment.

Yesterday, I've compiled the dvd plugin and the issue is still there. But I 
didn't use CVS for libdvdnav and libdvdcss, which are specified as 
requirement. Maybe, the issue has been fixed already in CVS, as Sven Gothel 
didn't mention anything about that.

I don't know, whether I'll manage it today, to get these two libs from CVS. 
Are you using the CVS versions?

Which application crashes (VDR or xine)?

In the case, that the femon plugin works on these channels, is the signal 
quality good or are there errors?

I have a broken NOVA-S (which needs to be sent in for repair, btw), that has a 
lot of errors on all vertical transponders for about 20 minutes after 
switching the system on. In that time, xine dies quite often. It seems, that 
the software decoder is not that fault tolerant, as it should be.
