From my experience...
First of all,
The best thing to do, is to uninstall the gnash plug-in (that, most of the
times, is too slow, or doesn't seem to work(?))...
And, then... For most YouTube videos, you can either:
- wait for the new HTML5 alternative to be loaded, automatically, once a
flash player is not detected
- or (if you want good quality on your videos), install the VLC player
plug-in for Abrowser, the "greasemonkey" extension for Abrowser, and the
"Linterna Mágica" script for "greasemonkey", and wait for all of them to be
loaded automatically, once you access a video's page on YouTube
(If the VLC plug-in doesn't load the first time, try refreshing the page in
question...)
The Linterna Mágica script, using the VLC plug-in, will also work with most
other video sharing web sites. And, it plays videos even better than the
proprietary flash plug-in.
