@Jock....
yah. i am able to view youtube with the application "youtube" & by opera mini... and using
http://keepvid.com/ , i can actually download youtube videos to my mobile too

......
One question.... everytime when I open opera mini and try to open a page it asks permission..... i always have to permit it to get access to any site (1 time per session). i tried to modify the "permission" java settings of opera mini. but it still asks permission.. any solution to give opera full access ???? it's very annoying

EDIT:-I have got the problem now..
(but, 50% solved)I am so angry on my
w995.... i was able to do everything on youtube (default thing in Media).... and previously I can watch in opera & default browser...
suddenly yesterday evening, when i tried to open youtube from "Media", it does nothing... (as if the application is not present there anymore

) i tried to open youtube in default browser or opera. it is not working and giving me message to install flash player and etc.....
I started to think what can be the problem. And i remember once i saw the link of the youtube pages in my mobile used to start as "www.m.youtube.com" ....... [Notice "m" in it. for mobile version.....

]
so, i put this address (with "m" in it) in address bar and tried to open the page.. youtube started to work in default browser & in Opera....
[Once you open youtube with the "m" in it, the site will always work... you don't have to put "m" in it from next time...
Until & Unless you click a link at the bottom of the page "View Desktop Version"

. if you accidentally press that, then use the "m" method again to solve the problem.]
=========
But i still am not able to solve the problem 100%, in Media..... I solved it 50%. but i am not happy with it.. I just installed minitube/youtube (java software) in my mobile. and i can use youtube in media..
But the problem is i always have to give permission to youtube (as it is not the default application which used to connect to igoogle server (youtube use it in mobile) and it is not rotating to landscape mode anymore

and the video quality of it s**ks....
===========
Does anyone have the original youtube program came with our mobile???
@Jock or any other guy herecan you help me out with this.... I am actually requesting you to extract all the files responsible for the
default youtube application came with our mobile originally (R1FA035) (it may be called iGoogle too.. not sure...... because it connects to igoogle media server directly..)... and which files are actually responsible for this application.....???
youtube.jad & youtube.jar files should be in \tpa\preset\default\java\... and i dont know where the other files should be in... (
probably inside system of Phone Memory).......
I have those 2 files (jad & jar) of R1EA028 firmware. but those are probably old version files. R1FA035 has updated version files......
One more thing, my default "WF Navigator" started to give me "buying warning". it tells me to buy it...

[though i still can use it...]
is it normal or my default applications got scr***d up???
