[vdr] Re: CRC Check with sections

[nisele@t-online.de (Nikolaus Isele)]

Hi Klaus,

i got still problems with my Allcam 4.6. in the Log i got "ERROR: CAM: Read
failed: slot 0, tcid 1" Messages. I don't have changed the hw_sections yet.
How can i change this? Is there a need for Updating my DVB-s 1.3 (primary)
and DVB-s 2.1 (secondary) Firmware? If yes, how? Is there a risk killing my
cards if i update the firmware?

Regards, Niko
