Hello
can you tell us which commit did fixed your problem ?

The ffmpeg version planned to be used for rpmfusion.org on F-8/F-9 is
FFmpeg version SVN-r13767 ffmpeg-0.4.9-0.47.20080614
For Rawhide (F-10), it will be ffmpeg-0.4.9-0.50.20080908.fc10 or later

This is more probable that the fix will be backported.

Some package from http://rpmfusion.org/ are available here:
http://download1.rpmfusion.org/, you might want to report feedback on
the rpmfusion mailing list
But please keep in mind that rpmfusion isn't officially opened.
(despite most packages improvements are made here).

ps: you will be able to find the 0.9.x version on my personnal repository for
kwizart-testing that are compatible with rpmfusion
