Psst. Perian is about to enter a private beta for version 1.1. If you recall, last time Perian went into beta mode the software leaked. This was generally a bad thing as a buggy and unstable version made the rounds, hitting Mac Update at one point, before the team was ready for it to go public. This time, they're reacting by limiting the beta list to users who have made donations and help support development. If you've donated to Perian, keep your eyes open for an invitation email.
