I think you may be mistaking what these units do.
Your Shaw Cable set top box will tune to the correct channel and decrypt
the stream. It's output is the decrypted stream. You can record it
depending on its outputs: firewire, component etc. If it only has
component output (which is actually 3 analog feeds) then the only way to
record it is to use the Hauppauge HD-1212...which does an analog-digital
conversion. Firewire would be straight digital. If you are lucku you may
have HDMI, but it may be HDCP crippled.
An HDHomeRun is a tuner + ATSC decoder with a network output. The inputs
are from an OTA antenna, or digital cable...unencrypted. You may be able
to feed your HDHR from your cable, but that depends upon whether Shaw
sends any unencrypted digital channels. Rogers in Toronto used to, until
July 2007, then made all digital channels encrypted. I now use an
antenna for OTA HD reception. It would be worth your while to see if
Shaw sends any unencrypted digital (BTW, the digital radio streams are
Your STB will have only ONE tuner and only ONE output.
