[vdr] encrypted radio with 2 (or more) DVB Cards

["Rienecker, Fa. Evenio, ITS P, M" <C.Rienecker@deutschepost.de>]

Hello to everyone,
using 2 DVB cards you'll watch payTV in so called 'transfer mode' provided that a CAM+Smartcard is attached to the secondary card.
What do you do with encrypted radio stations ?
It seems like (vdr0.99-pre4) the radio channel is tuned correctly but there will be no transfer to to the primary card.

Is that behavior intentional ?
Is the transfer mode of radio channels working with pre5 ?

Cheers,
Christian.
