You have a couple of options. Have you tried Linterna Magica? http://e-valkov.org/linterna-magica/ It is libre and it will help you play youtube with all free software. It doesn't seem to work if the youtube is embedded in another web page. They claim that it works on many flash websites, but I have had mixed results.
If you upgrade to squeeze, you can use Epiphany Browser to watch html5 video from youtube.com/html5 This doesn't seem to work 100% of the time, but maybe you will have better results.
The version of gnash in squeeze is quickly becoming outdated. It hasn't worked for me in youtube lately (youtube always seems to be changing things) and in other sites it doesn't work.
You could build the latest gnash from source. I did that when I was using gnewsense and it worked.
