Normally I would agree but there is no actual change. The old one played video and the new one plays video. What's changed? It's not significantly different in code nor approach. It's only been scaled down.
No actual change? Does removing all the assumptions (such as, audio files being converted to movies for playback) made over the last decade not count? They're getting rid of all the code bloat and old design (not to mention carbon code) that dates back to 1991.
I guess you missed my whole point about it being a framework. Quicktime is a platform, not a single application. You're raving on and on about Quicktime Player. Quicktime Player is just one part of the framework exposed to a GUI for playback.
Revising the QT platform does not mean making a better playback app. That's a bone they've thrown us before they deploy the new core into Final Cut and other dependent apps. It means revising the platform that app is based on. They're redesigning from the ground up to remove arbitrary limitations, hopefully enable better playback support (such as hardware decoding of H.264) and build better editing software in the future.
I hate to bring this up, but you're really starting to come off as looking every gift horse in the mouth. We all complain about 's decisions on this forum, but I can nearly always count on you to be at the front, with complaints that aren't necessarily valid. No, it's not everything we want it to be, but this isn't a feature that translates directly into dollars and thus is not a top priority. Same thing with ZFS. I'm not trying to be an apologist here, but it could be a Microsoft attitude - dragged kicking and screaming into new ways of doing things when threatened by newer free OSes. I see QTX as a commitment to update their older software into something much better, and given that you have the option of falling back on QT7, it's really hard to complain about it.
Should we have stuck with QT7 endlessly? Do you really want to feature bloat a playback app into an editing app when iMovie comes free with every system and sells two flavors of Final Cut to people?
