Here it is the code, remember it's just a hack to retrieve the URL and see if that can be played back, that is not meant to be production quality code 
Sorry for the ", but looks like it's the only way to make indent here.
Anyway the trick is to get the GDataService first and then make the query by means of GET HTTP requests.
In those GET yuo can provide a bounch of parameters to refine the search.
The Youtube GDATA API documents all of them exaustively.
The answer is an XML message that need to be parsed (and here the power of python helps a lot).
There was a python library, but Google updated the youtube API to adapt them to the Google ones.
The URL we're looking for, looks like its[1] in the <media:group> block for that video entry. Specifically the <media:content ...> tag.
The 'url' attribute is the RTSP stream URI.
(Other attributes will be useful when displaying it to the user).
So that's the easy part actually
Once I've got the URL we need to play it.
I've tried to call the GStreamer player with:
but with no luck so far.
Moreover, executing:
gives an error :

Wow.. the quote above makes the thread look very bad!
And the "edit" button is hidden to me!
UPDATE: Safari 3 renders the page correctly, while Firefox 2...12 does not. Great :/

playing with python a little i got this
http://www.postimage.org/image.php?v=Pq1EKPM9
double clicking will start playing the video after a 5% buffering
using the great mplayer port.
the gui is usable only by me
improvments as soon as i get some time.
a mock up will be very useful
PS: how do i post a image in this thread?

i did not expected such an interest for a a youtube player.
let's see what i can do.
I just checked IRC logs: his nick was tigrux.
Inz seems to have saved the testing packages he was hosting for tigrux: http://inz.fi/youtube-viewer-for-tablet/ . NOTE: These were testing packages, not meant for users. So don't blame me or the developer if something goes wrong...

My idea:
Youtube generates a XML file for a search:
http://googlesystem.blogspot.com/200...ube-feeds.html
I know a command line app that can download any youtube video or can be connected through a pipe with a player/encoder, mplayer or ffmpeg or whatever
http://home.gna.org/clive/
I want to integrate that in a GUI to make a youtube player
But If you want you can use the idea because I don't know a lot of development stuff and it can take me ages to do that.

that's what i have done in 3hours of coding last night.
i took a look at youtube-viewer_0.1-1_all.deb code.
it's pretty nicely written, it uses gstreamer and has a more complex approach, you can give it a try (check the link provided above by jussik)
i'm still stubborned enough to see i can i do with my app and i will still give it a try a few more days
