Last week while developing an OFX based awards presentation (OfficeFX is a 3D****) I needed to convert provided Quicktime movies to a supported format. No problem, open each movie in Quicktime Pro and Export to an .avi. WRONG – export errored out. I then spent the next several hours troubleshooting by installing, uninstalling, hacking option settings and registry entries – nothing worked.
A few days later I figured out the problem. I have been taking advantage of Vista’s ReadyBoost technology (using a USB memory stick as an extended memory cache). Turns out Quicktime’s export feature is not compatible with ReadyBoost. Remove the USB memory stick – export movies from Quicktime Pro. Now you know too.
