I have a question about streaming videos on the Nokia X6 web browser.

I was very interested in the Nokia X6 because of the streaming capabilities on the web browser. However, after purchasing the X6 i realized that the only website that streams videos properly is youtube.com

All my other favorite websites (liveleak, break, thatguywiththeglasses, ... etc) don't seem to stream videos. It just shows a little F on the top of the video but doesn't stream it.

I have the 16 Gb X6 version, i think i have Flash Lite 3.0 installed.

Can someone please explain to me why this is and if there are any solutions (codecs, or updates or something)

Thank you
