pmt pids get no data as long as I care to wait, but this is probably because
test_dvr doesn save anything before it has 65535 bytes

ca_zap does not finish, even when run before any of my code after a clean
reboot. There is nothing interresting in dmesg.

Telenor/canal digital, I do not know how they implement this stuff.

That's ok, I heard there is a hacked version of ca_zap flowing around that
does this. Is this correct? Could the hacks be integrated as an option

I will try that, I'll be back with the information.

Not upset, just mentioning it in case it might be related. I assume things
will play nice once I figure out how to use them.
