Joining the fun here, folks! My single biggest frustration -- that Flashplayer! To the extent that I have tried using various different Linux distros. It all began when I paid for a movie on Amazon. No go. Either Linuxmint version, or three different versions of openSuSE,(11.4, 12.1 and 12.2), PCLOS, Mepis, Mandriva and Kubuntu. Here's the joke: I can and do run and watch the various movie trailers on Amazon but the full-length movie will not, always giving me the message about my browser or flashplayer needing to be updated! Nonsense! If trailers run fine then why not the film? YouTube works perfectly as do various other videos in whatever format.
On the same identical hardware, using WinXP, that movie works fine so it's obviously not the computer itself. I even followed Adobe's advice and placed the various flash files into the appropriate directories (folders, if you like), and logic would conclude that the problem is not in my system but right there, at Amazon! How else could it all be explained?
Solution: when I get that urge, I boot Windows, watch my favorite movie, then log out and go play in Linux again. End of frustration.
Merry Christmas, all!
