IPhoto 6 freezes up requiring force quit - help!

Question

I loaded all my JPEGs and MPEG4s from my Sony DSCW1 onto 2 DVDS and imported them into iPhoto, creating new albums but keeping the DVDs as the path, ie not copying them to the hard disc. Now iPhoto starts up fine and works for a while but then a message comes up saying 'Cannot find MPEG 065', sometimes it's a different MPEG. It offers a 'cancel' option, but this doesn't work. The spinning wheel then starts and the iPhoto icon in the dock starts bouncing. The only command that then works is Force Quit. I can then restart it and it will work for a while until the same thing repeats. Any ideas?

Art2007:
That't one of the issues with the alias system and video files. You're better off creating a separate library for just the videos so as to not disrupt your primary library. iPhoto doesn't do that with plain image files that are referenced by just alias file.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've written an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.
