Hey, i have installed Ubuntu 9.10 karmic koala 64-bit on my system. It is powered by AMD Athlon and has a Nividia 6800 GT graphic card. Well my issue isn't exactly that flash isn't working. I have followed the instructions to install flash which works fine. I can watch the standard youtube videos and flash movies in the browser or in full screen. My issue is, i cant view movies or the content in full screen on my Ubuntu for some sites. Here is what happens, i press the full screen button to view the content in full screen,black screen pops up with a message at the top saying the advertisement will finish in 60 seconds, the timer won't work properly and in the end no video appears. One such site is demand5 where i have been trying to watch some episodes. Please help as i have ran out of ideas on how to fix this.
