RG-6 is the coax cable -

You don't
really need both connectors unless you plan to record a different channel while you are watching something else. The HDHR doesn't do 'Picture-in-Picture' - the Fusion does with dual tuners.
HDHR uses VLC and should also work with MCE on your Vista (I've never tried it with '64').
Using VLC with the HDHR seemed a little 'clunky' to me compared to the Divco Fusion interface. I had a separate window from which I had to select channels and I never grew comfortable with the recording setup
You should be able to connect it directly to your Ethernet port instead of a switch or a router.
That's actually good because if I tried to launch VLC from another node I would kick someone off the HDHR who was using VLC on another node.
And it was odd (in Vista Premium 32) every time I would change channels I would get another orange cone in my task bar - so if I was flipping through channels I would end up with 12 little orange cones - LOL - by moving my cursor over them they would all disappear (except for one).
So MCE it should be IMO with the HDHR ... Media Center uses the DVR-MS file format for recording, which is MPEG-2 video in a Microsoft proprietary file wrapper.
I'm really down on MCE right now.
PlayReady is pissing me off royally in Win7/MCE. It's killed my audio in my Fusion interface but in W7MCE scanned all my locals and works fine.
MCE in Vista is a whole 'nother can of worms. Everytime I apply the 'patch' something in my video/audio screws up and I have to to a system restore (and the Media Center TV Pack 2008 for Vista is only available to OEMs so I'm ewed-scrayed there).
The 'Zulu' encoders with Fusion always worked well for me (especially in XP). With Vista my system seems to force the MS "Unified Video Encoder'. It works but is not my preference (cpu utilization is sometimes 30% higher). I don't know if this will be the case with the HDHR on Vista.
I got this exterior
Low-Profile Omnidirectional Amplified TV Antenna on the cheap from the Shack in Cornelius 3 years ago - they were phasing the model out. Then I think they discovered how well it works for HD OTA so they brought the model back and jacked up the price 33% - LOL.
I painted it cedar-tone in color, nailed it on the side of the house (pointed in your general direction) and generally get 100% signal strength at 30%+ DBs. WTVI gives me trouble from time-to-time (I think they cut back their wattage) but I get channel 58 so np. I think I'm 18-20 miles max from the 'towers' (west of Hooterville in EL - when I'm down off the mountain)
I temporarily set it up for the little woman (in Old Providence) in tring to get her to dump TWC (it didn't work - dumping TWC - but the antenna did). Got all my regulars including SC PBS with the antenna hanging in a tree 7 feet off the ground - heh heh.
