I was able to recompile ffmpeg with the new option.

I had to use  libdc1394-devel-1.2.1-7.fc6.x86_64.rpm
for the configure accept libdc1394.

and .... It worked!!!

Maybe enable liba52 is for encoding and enable liba52bin for decoding?

http://people.atrpms.net/~pcavalcanti/srpms/ffmpeg-0.4.9-24_r8743.fc6.src.rpm

I also built the today's svn.

But some options changed, and I did not find any configuration option for
dts/dca (maybe it
is autodetected?). However, dca is listed as a valid decoder.

Please, see the changelog.

http://people.atrpms.net/~pcavalcanti/srpms/ffmpeg-0.4.9-2007108.fc6.src.rpm

The rest of it is up to Axel.

Have fun rebuilding it yourselves....
