About minitube, is it sure that it does not install any proprietary
codec/plugin? Totem has also a plugin which allows you to search by keyword
in youtube, the problem is that some of the videos do not reproduce while
other do (perhaps those with older formats?). On the other hand and
surprisingly enough, searching about minitube I have just found a script for
Greasemonkey called "youtube without flash auto" (I found it here
http://lifehacker.com/5428618/minitube-brings-a-flash+free-youtube-to-mac-and-linux
, comment by "nortexoid"). Anyway, the script adds some links under the
videos in youtube, offering to download, see without flash or with flash in
different resolutions. For the moment ALL videos seem to work (either with or
without flash). The script is published under GPL and can be found here:

Try it, I think it works fine,
Regards.
PD.- If someone understands coding, he/she could check if there some problem
with it (it is on the same page, of course.)
