True, although even linux apps/desktops associate extensions with
filetypes/apps, by gathering those extensions together as one type of
file. Take a look at the file associations under KDE and 'known types'
have a list of filename patterns like *.mpg, IOW file extensions.

Not enough IMO. I want to use mpeg4 and achieve at least half the file
size.

As it happens, I already have an older version of myth (0.18) on the
desktop machine. I didn't know you could just use it as a player.
Unfortunately it doesn't work when launched by file association under
KDE. Gxine, Kaffiene etc all work, but Myth just comes up to it's
normal menu when a recording is played this way from a file manager
(such as Konqueror). It mustn't play by the same rules.
