Is it possible to view streaming movies...

Try this;

Install .NET Framework.
Install Adobe Flash Player.
Use Opera.

You can get .NET Framework here:

The Adobe FP is a cab file, which is to be installed after you've put it on your device.
The .NET is an .exe which is to be installed on the PC:
1. Connect HTCTP to PC (via ActiveSync or WMDC)
2. Press the downloaded file (from PC)
3. Install and follow on screen information
4. Soft Reset

Viola!
(NOTE: This install takes some time.)

Adobe FP: There you go.

("Once you’ve installed Flash Player 7 you will be able to use Pocket IE to view Flash content embedded in web pages. There is no standalone player functionality provided with this install."
-Adobe
This means that if you don't succeed in viewing the file on Opera - Use Internet Explorer (IE) )

You can test it by visiting youtube.com from your Opera Browser.  If flash and .NET is installed correctly you will be able to view youtube from Opera. 


For your other site try viewing it using the skyfire web browser.  To get that go to m.skyfire.com
