Digital Devices ddbridge with vdr + dvbapi+oscam

Hi,
does anyone have some hardware from Digital Devices (Max S8, Cine S2, ... ) and is able to decrypt 2 channels at the same time and maybe from the same transponder ?
I have tested some distributions and no luck till now to get it working stable with more than one recording channel.
Is there something needed as patches to the default installed distribution/vdr/receiver-card-firmware to get it running to decrypt more than one channel stable ?

sometimes it works with more readers but sometimes not :-(

Hello FunThomas.
I can confirm now that I have DVBAPI + OScam and it works just great with my DD CIne S2 card (4tuners). 4 concurent streams are being decrypted by DVBAPI. The setup is stable.

thanx for the answer, i think on my system dvbapi+oscam have a race condition problem, if i enable dvbapi loglevel 3 then it works fine too
