Stop using this base64 encoding!
It means:

Hi,
    I guess the old versions of the driver before ver0.9  support =
various CAMs significantly.Now that the cards from skysat also seems to =
be vesrsion 2.1 and even newer.I think the diference between the old  =
version and new version  of hardware is only in the tuner and =
demodulator.But the old  driver version does not support new hardware =
version.
If so,I think there are is a possible way to workaround the CI problem =
. As follows:
    "backport" the driver for STV0299 etc to driver version 0.81 or =
even older. because the new version hardware takes STV0299 to as =
demodulator and the old version driver does not support this.In this =
way there is nothing to do with the Firmware.
    Somebody in the mailinglist has also upgraded the driver version =
0.81 to support linux kernel 2.4.X above.If something can be done with =
new hardware version,i think all of our free users can get a stable =
version of the driver which can run on NEW hardware NEW kernel versionn =
and support VARIOUS CAMs.
    But who can tell me wich version of the driver is stable enough and =
support various CAMs?

Wish this mail will not  run error to the mailinglist.
