It's my understanding that Analog OTA is supposed to have been discontinued, except for limited, low-power applications. I don't even have an antenna anymore to check. Are there still any NTSC TV broadcasts?
No, there are not. Laptop cards are ATSC tuners. Digital.
Have you had any success using any of these lower-cost netbooks with USB tuners? I know that just trying to watch HD video streams on my Atom-based EEE-pc can often be unsatisfactory.
Yes, but you have to drop the frame rate a bit for 1080 content. Also, Windows 7 is better in terms of resource usage.
It's a darn shame we went with ATSC and QAM here in the USA, because the DTB-T and cohorts used in other countries is
so much better and easier all around and addresses things like mobile access.
See
http://en.wikipedia.org/wiki/DVB-TThere's also DVB-S2 -
http://en.wikipedia.org/wiki/DVB-S2 With that, you can connect a cheap-o sat dish and still get a signal well out of range of terrestrial signals. It's amusing to me (in a kind of dark way) that I live 2 hours from 2 major cities and my over-the-air reception of television is utterly lacking, yet if you're in the middle of nowhere in any of Europe and much of the Mideast and Asia, for a few hundred bucks, you get plenty of signals from a cheap disk and simple hardware - and plenty of Free To Air (FTA) programming.
