Further to my earlier post (media player on linux), I have discovered that the netbook has VLC player already installed, but there is no link for upgrades, and I receive a message when I try to play .avi files: "cannot find codec matching selected -vo and video format 0x444956582." I am wondering how to update the VLC player to the current version (i.e., in which folder should I download and install the program), and if downloading the recent version will actually fix the problem of the missing codecs. If it will not, could someone possibly tell me where to locate the missing codecs and how to install them into the correct folder to get the player working? Florio
