series airing in hdtv

[posix]

where to get trustworthy information what series currently running are aired in hdtv?
it seems many people misunderstand hdtv as a resolution-only thing, upscale their releases and call them "hdtv".
see nana or black lagoon, for example.

so, anyone know where to find like... a list of hdtv series?
