For this I get:
Picasa Help - What are your technical requirements for uploading videos?and no status updates or acknowledgement that iPhoto 2008 has broken the Picasa Web Album iPhoto plug-in.
Video uploading is only available through Picasa.
I'm definitely feeling like a second class citizen on Google's Picasa web albums.
It doesn't help that Google Video is out of order today as well - no uploads (server failure).
.Mac is looking better these days.
