Hi Oliver,

the patch fixed the problem - here the relevant part of the log:

Aug 24 09:40:07 vdrdev user.info kernel: [   13.943338] DVB: registering new adapter (TT-Budget/WinTV-NOVA-S  PCI)
Aug 24 09:40:07 vdrdev user.warn kernel: [   13.966605] adapter has MAC addr = 00:d0:5c:23:72:54
Aug 24 09:40:07 vdrdev user.warn kernel: [   14.064407] DVB: registering frontend 1 (Samsung S5H1420/PnpNetwork PN1010 DVB-S)...

Thanx to all - also to Dr.Seltsam for compiling.
Eberhard
