Hi,

Running a bunch of test with gnutv and a DuoFLEX S2.

I saw the same problem concerning the decryption with a CAM.

I'm running kern 2.6.39 rc 4 with the latest patches from Oliver. Also
applied the patch moving from SEC to CAIO.

I would run gnutv  like 'gnutv -out stdout channelname >
/dev/dvb/adapter0/caio0' and then 'cat /dev/dvb/adapter0/caio0 | mplayer -'
Mplayer would complain the file is invalid. Simply running simply 'cat
/dev/dvb/adapter0/caio0' will show me the same data pattern over and over.

Anyone using ngene based card with a CAM running successfully ?
