Oh....please....please....no more HD-DVD vs BD debates. That format war is over. I'm glad I stayed on the sidelines until it was over, so I didn't have to join the debate.
Overall, like most AV equipment, the manufacturers are trying to build to a price point. Shortcuts develop (processing power, memory, etc).
Still, that doesn't account for how the ubiquitous PS3 seems to have got it right, at one of the lower price points for BD equipment, while other companies just can't seem to do it.
IMHO, we're in 2nd, 3rd generations of some players. It should be clear on a hardware, and software side, what's needed.
Audio HD codecs have been out for a bit, now. Issues should be behind the manufacturers since those codecs haven't changed since they've been released.
The enthusiasts here on these threads do indeed want to wring everything possible out of the format. My guess is, the guy (girl) who goes into BB, CC, etc just sees all the formats on the box under the displays, and buys the one that has the most "logos" on the box. Little regard is given to whether the unit they purchase actually does what it's supposed to do.
When the unit freezes, hangs, audio drops out, they just schlep it back to the store. Maybe they even give up on the format and stick with their trusty DVD player that they bought for $70, figuring that $300 BD player isn't worth the hassle.
Music so high you can't get over it....music so low you can't get under it!
