The only way to use your cable box to get HD onto your Myth box is to use
the firewire output on the box.  This will probably only give you the OTA
stations.  Cable channels are generally encrypted  and unavailable to Myth.

You could also get an HD capture card and leave the cable box out of the
loop.  This will also only get you OTA channels (whether the signal is QAM
from the cable line or from an antenna).

As far as getting HBO, TNT, etc. onto your Myth box in HD, you are more than
likely SOL.

The cable box will downconvert your HD channels to NTSC and put them on the
S-Video output, which can then be captured by one of your Hauppagge cards.
This offers marginaly better picture quality than capturing the analog
versions of these channels straight from the cable line, but it will still
look like crap on your TV.

At any rate, search the archives for info on this topic, there is plenty
