I've seen a few posts in HD Talk discussing upcoming TV shows in HD. Wouldn't they be better suited in TV Talk? I personally hardly ever go into HD Talk as I do not own any HD hardware or media yet.
And if you note the sections on the Main Forum page, it has DVD Discussions, and under that is HD Talk, which implies HD Talk is for HD/Blu-ray DVD's not TV shows.

Anyway, the ones I've noticed are:

Star Wars in HD on Cinemax

Why HD-DVD release announcements don't stress me out (aka HDNet Movies for November)

OK, this one is borderline, as the OP starts with reasons why he doesn't mind waiting for HD DVD's.
But I never saw it posted, and only found it on a search before I was about to post the list of HDNet movies for November. It looks like most of the discussion is about HDNet movies/TV.

They've been posted for awhile, and doesn't look like they are moving.

I think they should just go wherever they are posted, and it would be fine for threads to exist in both forums.

The HD Talk forum description is pretty general: "The place to discuss HD-DVD, Blu-Ray and all other forms and formats of HD and HDTV."

Thus discussion of HDTV programming falls under than umbrella.

But at the same time I'm sure not everyone who has an HDTV reads that forum as I'm sure all the fanboy bickering keeps many away so I think it would be fine for people to also post lists of HD programming in TV forum threads as well.

Just my 2 cents on the matter.

I don't have either HDDVD or BluRay and have pretty much always thought the HD forum was mainly for that discussion.

I watch HD all the time and would prefer discussion of HD on TV be in the TV forum. But, that's just IMO.
