Why do I need to install QuickTime 7 ?
VideoDrive 1.11 and higher is a new optimized version of VideoDrive, running in both 32 and 64bit for better performance.
Snow leopard includes a new version of QuickTime, version X. QuickTime Player X is a front end to this new technology.
This player offers offers fewer conversion and save options than were found in QuickTime Player 7. Therefore, QuickTime Player 7 must be present on your system in order for VideoDrive 1.x to function properly.
Installing QuickTime Player 7 will not affect the underlying QuickTime technology in Snow Leopard - that will still be QuickTime X. You are only installing a different front end to QuickTime X, one that offers more export options.
VideoDrive 2.0 (available soon), does not require QuickTime 7.
