Why does Warner favor Harry Potter on HD DVD?

[quexos]

I have read on Highdefdigest that the hd-dvd version will have some kind of interactive IME where people can connect at the same time they watch the movie and one host can control the movie ?
I'm not too crazy about that option because when I watch a movie I don't want someone else somewhere to pause, stop, fastforward MY copy on MY tv through the internet and as far as I understand, this is the equivalent on Bluray of BD-live which is not implemented so far (by the way, why ?)

But the second favor Warner will give hd-dvd is PIP commentary wich will be exclusive to hd-dvd and won't be on the Bluray version. This one I would have liked to have. Don't get me wrong, I would never get the hd-dvd anyways, as I actually went to France today to get the Harry Potter 1 to 4 on Blu today which I planned to do anyways. (Cause it won't be out in Belgium until January)

But WHY is PIP exlusive to that crappy format ?????

PS: as I was in Lille today (France) at the biggest store downtown called FNAC, they had these 4 spaces for HD, 3 were for Blu and only 1 for hd-dvd
