OK, here's the simple

explanation.
There are two kinds of cable.
Analog cable which requires an analog tuner (Hauppauge PVR-250, etc).
This will get the most channels, but NONE in HD
Digital cable. This is a little more complex. You CAN use a cable box,
connected to an analog tuner (like the PVR-150 or 250) and get ALL the
digital channels, including HBO, etc. ALL will be in SD.
A QAM tuner tunes digital channels, without a cable box, but ONLY those
that are unencrypted. Almost EVERYTHING is encrypted by most cable
companies, including HBO, TNT, etc. SO, the HDHomerun is ONLY useful
for your LOCAL channels. They should be on your basic service, in QAM
format, BUT (and it is a big but), they could be in SD, HD or both. For
example, Brighthouse in Orlando only provided SD even though they could
give HD. Mediacomm here in Iowa provides HD.
So, it is a bit of trial and error.
There is currently no way to record ENCRYPTED digital content (including
HD) except with Vista and a digital cablecard tuner. These tuners can
ONLY be purchased with a new machine (including the XPS420) and they are
very expensive. IN addition, you have to get a cable card (or two) from
you cable company.
Not sure all that helped.
