been thru everything I can think of (incl. VLC etc etc etc), but seem
to have resolved the issue by looking at other authoring
environments - Director was crap, Livestage limited, but iShell -
well - nice:) It must be a timebase issue and the way the app (QC)
addresses independent timebases. A pity after all the programming
that went into the quartz version, but them's the breaks. I have yet
to fully test this on the G5 (runs fine off the powerbook), but it
saves me a heap on new graphics cards, RAIDS or computers (and YES -
I've checked out a few configs there - all very fast in quicktime
(cache/RAM) and disk-read).
iShell, could, of course, have a GUI like QC - it's so nice (but get
rid of the limits on the window size in the composition (QC) - too
much scrolling!)
Anyway, I will report back & thanks everyone for your generous time
and thoughts.

I don't think that's a HD problem. To me it sounds more as if QC is

bottleneck. Because this movie should playback on a MacPro even
uncompressed
w/o any problem.
Peter, have you tried to playback the file in VLC? Were there any
differences to playback in QC?

What kind of harddrives are you using to play these back?
Typcially, for HD
resolution and uncompressed playback you need around 200MB/second,
which
requires something like an XServe Raid or other high speed disks.
You can
minimize this throughput need by using compression, but you'll
still probably
need some decently fast disks for files that size.
