[Qt-interest] Qt Online Training Materials, some Video goes, some not

[Thomas Meyer]

Hi,
I hope my post is here right?

Following happens with the Opera browser on:
http://qt.nokia.com/developer/learning/online/training

When I choose: Widgets
http://qt.nokia.com/developer/learning/online/training/specialized-elearning/qtwidgets 


and play for example the first video:
http://qt.nokia.com/developer/learning/online/training/specialized-elearning/qtwidgets/widgets-common-widgets
Opera crashes.
But when I choose:
http://qt.nokia.com/developer/learning/online/training/specialized-elearning/modelview
or
http://qt.nokia.com/developer/learning/online/training/specialized-elearning/modelview2
all videos play well.

Conclusion: All videos from Oliver Gutbrod can I play with the current 
Opera browser, all others not!

Any hints?

Opera Version;
Version 11.10
Build 2092
Plattform Win32
System Windows 7

Thanks,
     Thomas
