My friend wants a distro which will be able to play most of the proprietary media formats out of the box. The reason is he doesn't has internet connectivity at his place. Do note that the distro should be able to play not just simple files like mp3, avi etc but also more complex one's like .mkv, .mp4 etc. I suggested him Linux Mint & Sabayon Linux but I doubt about their ability to play .mkv & .mp4 formats. Which distro you suggest for a computer with no internet connectivity?
