I've had limited success with it. I can now receive all the channels that you typically would, when bypassing the Media Box and plugging the coax cable directly into a normal TV.
However, the picture quality is pretty bad - very grainy. As I said in the first post, it's not the coax cable, as the picture is clear when plugged into a normal TV. I just don't think the PC Tuner I got is up to the job - It's a Pinnacle device, by the way, if you feel like avoiding it when shopping for one yourself. To their credit, though, I did chat online with one of their techs, and the guy was as helpful as he could be. Unfortunately it doesn't really matter much if their products suck.
To answer Etherm's question, I have the UPC HD Media Box, without DVR. It has all the standard interfaces, including HDMI. However, I would recommend going for an External DVR along with the Media Box, and not the UPC one, if you can afford it - if you set it up (i.e. cable it) properly, you'll have more choices for recording one programme while watching another. And of course, recording directly to DVD, editing recordings, etc. I have a Pioneer 630H, which is a couple of years old now, but I think it's one of the best AV components I've ever bought! If\when recordable Blu Ray devices are available (waiting 'patiently') I'll upgrade, but until then the one I have now still has plenty of life in it.
I have connected UPC analog cable to MCE 2005, Vista MCE and Mediaportal. Its pretty straight forward. Connect the antenna from your wall to the analog tuner card. Don't scan for channels. In all three systems, you should select analog cable and specify your city and it will give you a drop down list of providers. Select your provider and it does everything automatically. Oh YOU MUST make sure you have a working internet connection on the MCE box so it can download all the provider info. It then uses the internet connection to maintain its EPG data. Scanning for channels manually results in poor picture quality and poor channel identification with no benefits. If the cable company changes the channels on you, just go through the setup again and the programs will download the latest frequencies automatically.
I record all analog content within MCE and then use TMPGENC to convert to m4v h264 and remove ads. its a manual process but I get small nice quality files. HD on UPC is just not worth it yet. There isnt enough content.
That said, we pretty much don't watch cable TV anymore.
