I'm working on a migration path from the video module to the filefield module (using jQuery Media for playback). In terms of database language, I'm a Filemaker hack so I'm seriously struggling with many aspects of mysql, but I think I have laid out a good plan for attack and have a really good starting point to work from. I'm basically adapting a migration script that Moshe built for us at CCTV to migrate from the Image module to Imagefield.
Please drop by and check out the work, try to proofread my work, and fill in the gaps that I can't do. It would be awesome to get this working, it would give users of the 5.x-dev video module a path to migrate their sites to filefield and ultimately update to Drupal 6.
Thanks in advance!
