Warning: Loads of technical details!

I think you have run into a problem I spotted some time ago. Digital Everywhere have (or had not at that time) implemented support for ca_info in their firmware. This means that there is no correct way to check with the card what ca_system_ids that the CAM support (Viaccess, Conax, Irdeto, etc.). What I did when implementing the CA support was to use the field from the application_info message called application_manufacturer since those IDs tent do be the same in many cases. However it seems not in your case. At least I believe so since your PMT message seem almost empty.

Many applications does not care what ca_info contains but MythTV is one that does. This means that MythTV does a check of the ca_system_id received in the CA_INFO against the ca_descriptors in the PMT and throws away all non matches. Hence your PMT is almost empty from MythTV.

However, I have created a patch where you can fake up to four ca_system_ids returned in your CA_INFO message. It can be found in the link below and is called "0001-firedtv-add-parameter-to-fake-ca_system_ids-in-CA_I.patch". Try to apply that and then set the parameter fake_ca_system_ids to your ca_system_id. Since you are using Boxer, your should have the Viaccess id, which is 0x0500. I.e.:
# echo "0x0500" > /sys/modules/firedtv/parameters/fake_ca_system_ids

Hope this helps you get further with Myth. Have a nice birthday!

Thank you Henrik! That was a great birthday gift

Worked perfekt.

# echo "0x0500" > /sys/modules/firedtv/parameters/fake_ca_system_ids
was:
# echo "0x0500" > /sys/module/firedtv/parameters/fake_ca_system_ids
