Failure on some streams (no crash)

[Alex Eskin]

(Sorry if this gets posted twice.)

On some sites the flash video stream does not play, even though there
is no crash. The same stream works with a native flash plugin.
The only test case I have at the moment is www.cbs.com/video
(which is AFAIK not accessible outside the US).

What does not work:  fedora 9 with all the latest updates on x86_64, i.e.
nspluginwrapper-1.1.2-2.fc9.x86_64
nspluginwrapper-1.1.2-2.fc9.i386
firefox-3.0.2-1.fc9.x86_64
flash-plugin-9.0.124.0-release.i386
libflashsupport-000-0.5.svn20070904.x86_64
libflashsupport-000-0.5.svn20070904.i386

If I install flash-plugin-10 and remove libflashsupport, I get exactly
the same symptoms.

What does work:  ubuntu 8.04 with all the updates on i386.
This means firefox 3.02 (or 3.03), flash-plugin-9.0.124,
and the plugin is run natively.

What can I do to track this down?

Thanks,

Alex
