Can't play 1080p videos on Youtube but they play flawlessly on Windows 7. Any suggestions/help? CPU: AMD Turion 64 x2 1.8GHz, 2GB Ram and ATI HD 3200.
Are you using Flash or HTML5?
Flash - there may not be a solution. Flash for Windows is much more optimized than Flash for Linux.
HTML5 - do you have graphics acceleration enabled for your graphics card? If you can play 1080p in MPlayer or VLC, then it should work with HTML5 on YouTube.
