Just one more point, in case I wasn't clear on this:  the HD-PVR only
captures at whatever resolution the settop box is outputting.  It has
no onboard video scaling capability.  So if the video is in a lower
resolution and it's well formed, then it's because that's what it
received.  Whether that's because you're recording from the wrong
channel or the cable company is putting out SD on the channel you
expect HD, I'll leave that up to you to figure out.

In short, it's not a driver issue.  :-)
