Just in case you haven't noticed, the version of QuickTime supplied with OS X PB is actually QT 5, only they've given it the version number 4.something-or-other. It has all the features, and faults, that QT 5 has.
Although the fact that they don't just make one version to work on both platforms is somewhat odd.
Why get a G3 when my 1.5 year old G3 still kicks ass????
Apple should do a better job at making QT on X better.
I hope that QT provided with OS X final will be much better
and will have more functionality than the QT in OS X now.
Personally for the time being I use QT 4 under classic
Yeah, but there are limits. After all, in Classic the computer only had to run Quickdraw. Now the drawing system is handling compositing and antialiasing on the fly, which is why drop shadows show up over Quicktime movies.
Furthermore, a lot of work is going between processes because the window server is a seperate process, so there's overhead there. All this means that it's never going to be as fast, but it's far more flexible and reliable. In other words, get a G4.
