MOV Files from Olympus Cammedia impacting performance

[Guest matt]

Help: I have transferred a number of .MOV files from my Olympus camera. I can

play the videos via a number of readers/players. However when I view the

files via explorer, Vista file system or my Olympus master software, the hard

drive churns away and 'program not responding appears'. It appears as if the

system is trying to individually read each movie before its displayed.

Photographic images without .MOV files within these directories appear

immediately (I have indexing turned off). Eventually each .MOV thumbnail

appears but this can take 20+ minutes if there are several movies in the

folder. Removing QuickTime from my machine resolves the problem completely

but then I am unable to view my movies. I have a installed the recent VISTA

patches but this does not address the problem. FYI I have a DELL Core Duo

6600 with 4gb of RAM and a 320 mb NVIDIA card. Any help much appreciated.
