have much more sensitive tuners than those attached to my Myth box. I
currently have 1 Hauppauge HVR-2250 and 2 Pinnacle 800i cards. The receivers
in the Myth tuners need much greater signal levels than the tuners in my
TVs. In fact, I split my cable line (4 ways) to send an equal signal to all
my recorders. I then split one leg of that (3 ways) and send the very
reduced signal to my TV sets.

My first guess would be the Sky box or Foxsat have more sensitive tuners
than the ones in the Hauppauge devices.

Cheers,
James
