This is strange and i have no clue why it's happening (maybe it's the hard disk)
if i try to play a "huge" .mov with high resolution/uncompressed, the playback is skippy (a lot!).. almost pause every 1''
if i boot with a xp and i copy the same file (.mov) and try to play it with window's quicktime the playback is ok,even full screen.
XP are installed in a fastest HD than Leopard but this would not stand such a big problem, would it?
anybody know why is this happening/anyone can test it?
i mean about .mov files with resolution like 1980x1200 and a lot of layers/fx stuff inside, created with a video fx program (after effects,motion etc)

specs are in my sig
perfomance in my system is normal for my hardware
xbench results without disk: 270
the disk alone i think that gets: 40

In XP with HDTUNE i have this results for both disks:
XP Disk: 81/maximum
LEO Disk: 47/maximum

so ok the osx disk it's not that f*cked up, it's a normal UDMA5 IDE disk (not SATA)

but it's uncompressed quicktime movie :wacko:
when it's uncompressed there is no bitrate and whatever
only quality,millions of colours etc
codeck it's the normal apple's codeck for quicktime maximum quality

anyway i start to blv that if i move to a sata disk things will change :unsure:
