Quicktime is a major platform, protocol and application in the audio video world, not some obscure toy. I have no idea why the user forum has a slew of bad comments. I know of no general negativity against it world-wide. If nothing else, Quicktime Pro enables download -- as opposed to immediate stream -- of videos, such as movie trailers, rock videos, etc., that are embedded on webpages. I use it on three OS: OSX - Tiger Windows XP Home Windows XP Pro (totally different than home) on three different CPUs, AMD, AMD+ and P4. Nary a problem. ::::: Opera :::::
