I was pondering this very issue just last night at work. I figured I can build a nice HTPC using Windows XP MCE 2005 with an ATI HDTV Wonder onboard; therefore,
Numerous Specialty/language/news channels (mentioned before and not available OTA)
True, but as stated above, PBS has some very good programming lately, in fact I have found more interest on PBS than on Discovery.
With an HTPC services like Cinema Now allow you to "rent" movies and they download to you just like VOD does.
IPG (I don't believe)
All the ATSC STB have IPG and so does Windows XP MCE
You are correct here. Although some people may get enough of their sports fix with Fox and CBS.
The LG LST-3410A is a HD ATSC STB with DVR --> http://us.lge.com/Product/proddetail...tegory_level=3
Also, again with HTPC the ability is built in and endless.
I myself am considering HTPC to compliment my Starchoice receiver as opposed to buying the DSR-530; sure it will not record satellite in HD but I think DVD quality is sufficient if I need to record off satellite to the HTPC. All OTA recordings will still be HD or SD depending on the source material.
Very interesting article here on "The Green Button" a site devoted to Windows XP MCE talking to 3 Microsoft developers which gives you a "feel" for their direction. --> http://www.thegreenbutton.com/conten...ame=ThomasHawk
In short, if all you watch consistantly is "Network" programming like I find myself doing time and time again then OTA may be a substitute for paid programming from cable or satellite.
