I'm pretty sure if I'm following HD spec, it's HD.
And yes, it's being delivered "over the web". But tell me, what do you think it takes? I don't think the feat is very miraculous, frankly.

The challenge is how to get high-definition TV signals into a computer, without hooking it directly to a cable line.
HDTV is a HUGE bandwidth hog. Transmitting HDTV signals in real time, using usual MPEG-2 compression standard, means sending data at 18 to 20 megabits per second. The typical user connection, delivers data at only 1.5 to 3 Mbps, of course there are faster out there but we are talking typical.
Even with new compression format, MPEG-4, it's not just a compression issue, it's an issue of transporting the signal over the Internet. In order to get around this issue some companies have adopted proprietary players (an example is VUDU) that use buffering and error correction to compensate for the lower speeds.
I think this is what A1r3k is referring to when he says most people do not know what it takes to view your content in HD
