Tvheadend

There are some digital channels that are not encrypted but also many that are encrypted.

The constellation for the encrypted ones is QAM/256.

One can purchase the channels through a package, through a COMHEM-MODULE and then a card in the module. I believe the codes would be contained therein.

EXAMPLE:

These channels comes from the wall at home, so I think they should be encrypted the same for all customers, and not unique for us, although I have no idea. It's possible it's per user, since they would continue to be available otherwise if one terminates the subscription.

1. Is there a way to crack this code? I've seen some websites, but nothing for COMHEM SWEDEN. http://satellite-keys.ru
2. Is some USB TV based TV module that works with TVHeadend that can get the decryption keys from this module, like my TV obviously can?

What solutions are there for this?

I appreciate your thoughts.
