I left a comment, suggesting they check out the rest of MediaPortal as an alternative front-end while they are looking into the Media Portal TV Server... (awaiting approval)
I'm also a US MediaPortal user. The TV server works fine for me and I've setup US free EPG using xmltv/mc2xml and WebEPG with imdb.com. It took a fair amount of groping through the forums to find the setup info. Around 85-90% people in the US pay for cable for TV. I'm in the 15% that uses over the air ATSC free TV.
Hey Ray, I too, left a comment on that old survey post, I never saw it show up either, this last post was a tutorial/promo specifically for XBMC.
The survey page has an option to show ALL discussions, and expand individual threads, but I don't think yours or mine showed up. There was, however, a Mediaportal user that mentioned more about what they didn't like about MediaPortal than what they liked about it
