Ubuntu does not have a video problem. I can run any video file in Ubuntu. If you
can't then you may have to install missing codecs or applications. Unlike some
Linux distros Ubuntu in recognition of copyright restrictions does not include
restricted drivers and non-
foss software. Some distros don't care and install copyrighted and restricted
drivers and multimedia codecs by default. Depending on your own ethics regarding
this, you can choose to install or not install. In Ubuntu you must change
Synaptic's settings to allow restricted repositories.
