"Portable Copy" PS3 firmware functionality appears from nowhere
PCWorld - that most reliable source of PlayStation 3 firmware-related news - is claiming that version 2.20 of the console's software "exposes 'Portable Copy,' which enables PS3 users to copy a standard-definition version of the Blu-ray movie to a PlayStation Portable (PSP)."
There's no mention of the feature in SCEE's press release about the firmware update, so it goes under "rumour". Bear in mind that in-game messaging wasn't included in the release and isn't in the update, so don't hold your breath on this.
