Well, simply because it does not work from within MythTV... :-)
All it gets me is 'no file' recordings:

Myth start the recording and through MythWeb I can see it thinks it is 
recording but there is no file.
All other things like getting the EIT data  work ok even as recording 
from the few unencrypted channels.

In the backend logs there is only this:

And then nothing..
I already tried al kinds of tuning timeout values but to no avail. Since gnutv records just fine when ordered to do so I reckoned if I would connect the recording event to gnutv it would work without digging deep into the problem. Ziggo is one of the largest cable provider in the Netherlands but they use a non-standard form of DVB-C, even channel scanning is hopeless: they transmit transponderlists for all networks, not only the network you are on. You need to enter a seperate network number on their hardware decoders to make it store the channels available on your local network. In MythTV by entering each transponder manually I can get the channels I want.


P.S. googling on FireDTV and Myth is no fun as all I get are links to 
'how to disable FireDTV' as there seems to be some conflict with another
