Warner was testing. HE DVF had online features and HDi and BR had 2 features in HD. Not surprising.

Testing to see what? If people had a choice of both, if they'd pick online functionality versus HD extras? If that's really what they were thinking, that's astonishingly stupid.

Its hard to type a whole conversation on my iPhone, lol.

Warner had special features exclusive on both formats. Testing i.e. seeing if online would help sell the HD DVD version of Blu-ray. And the Nielsens showed Blu-ray sold slightly better then the HD DVD version, meaning maybe online function was more important (since Blu-ray has a much bigger install base, it should have sold much better, like 300 a few months before). Of course we will never know, and Warner could have easily issued a second disc with the two HD features on HD DVD if they wanted (if space was the reason on HD DVD). They issued two discs for Clockwork Orange on HD DVD.

I don't mean to seem contrarian, but for the sake of clarity, there are three HD extras on the BD, not two (Focus Points, Deleted Scenes, and Trailing Tonks).

There is also an additional 45-minute extra that is exclusive to the BD, but it is in SD, and I kind of suspect that it is roughly equal in size to the exclusive PiP commentary on the HD DVD.

I just don't see how this approach would prove anything. The only way it'd show any evidence of anything is if the majority of people owned both Blu-ray and HD DVD players, and the only difference was in the software.

If you only have an HD DVD player, you're probably going to buy the HD DVD version no matter what the difference in extras are. If you only have a Blu-ray player, you're probably going to buy the Blu-ray version no matter what the difference in extras are.

Another reason I have a hard time buying this explanation is that for all intents and purposes, anyone who has a Blu-ray player will be able to take advantage of high definition extras. I don't think having an HD DVD player connected to the Internet to watch a movie with other people around the world holds remotely that same appeal. Maybe if I were a regular on a Harry Potter fan forum or something, but anyone else...? If the extras aren't at least equal in appeal, I don't see what it'd prove, especially if the differences in extras aren't being heavily marketed.

How many people even knew in advance what the differences were? If the differences weren't marketed or made very clear, that wouldn't make a meaningful difference in anyone's purchasing decision.

Just going with the Occam's razor approach, it's a much more reasonable explanation that Warner couldn't fit all of this HD content on one disc and, for whatever reason, didn't want to shell out for a second.
