[mythtv] hack for using removable with mythvideo

[Leo Weppelman]

Attached is a quick hack to use the stuff on an inserted cdrom
in the video browser. The hack assumes a '/cdrom' mountpoint.

This is a quick hack, since I am unsure what the 'desired' direction is
for removable media in mythtv. For things like a video-dvd, audio-cd and
[s]vcd, things are reasonably simple, just fire-up the required player
menu (like this currently happens for dvd and [s]vcd). With non standaard
cd's and dvd's, it looks more complicated.

When playing with the dvd-player at my parents house, I found out that
when the player was confronted with a dvd that contained an iso9660
filesystem, you ended up in a filesystem viewer. When selecting a node
in the filesystem with a known extension (mp3, mpeg, avi etc...), it
started the required player. This worked reasonably well in practice.
It would have been even nicer if it was displayed on the lcd-display,
so I wouldn;t have to turn on the tv, when I just wanted to play some
music.

One could make this approach more intelligent by scanning the filesystem
for file-types first. And when it turns out that the dvd contains only
video data (.avi, .mpeg, .nuv...), you could be dropped into the video
browser.

I am throwing this into this group since I have a bunch of cd's and
dvd's that I'd like to use with mythtv. I don't mind to put some work
into it, but I hate to do work for naught since it will never get
accepted into cvs (I hate maintaining large personal patch trees ;-).

Just seeking opinions,

Leo.
