I'm not familiar with the t.rex, but if you have enabled multirec you
can test it easily on your system. You remain limited to same
transponder and same polarisation.
 
It does not seem possible to use the CI/CAM of one tuner to decode a
stream from the second tuner. Some commercial STB tuners can, and are
permitted by my provider to do so even. Pity, because I use two CAMs on
my DVB-S receiver card as well.
