Has both sd, podcast and HD content for downloading/viewing using their player, check out buytv channel for 720p content (just an informercial channel, but looked pretty good on my pc) in something they call iHD. You can schedule you subscriptions to download autmatically when available.

I'm not endorsing the site, I just think this is where the future is going for a lot of us. Not that IM.com is the only way to do it.

p.s. this is not a streaming site, you download content and play it locally.

that's pretty interesting... there are a lot of companies hitting it from all different angles... dave tv, akimbo, current tv, etc... it'll interesting to see what shakes out.
