Hi, I have a problem trying to install and play some CD-ROMS with coarse material I need to study. I have the AAO with Linux and an external CD/DVD drive, I load the disk into the drive and then click on my documents, then click on the disk in 'my disk' then open the file. Then i get this message 'cannot find codec matching selected -vo and video format 0x46365056'. Please can you advise what to do Regards Runway66
