Here are some links: video.google.com, www.revver.com. This one is a newcomer but truely amazing: www.seetoo.com, there is no cap on the file size!
I hope that helps,
2 weeks ago I bought a new SanDisk min SD card 4.0 GB, that was a major upgrade to my old 1.0GB. I was able to take very long video clips with my Canon powershot. Problem that I?m having now: I have about 10 GB of videos and stills (mostly video) that I want to send to my sister. What?s the best video sharing service out there that can handle these sizes? I tried YouTube and Picasa but it?s almost impossible uploading something greater than 200Mb (I have some 700MB files).
