I had some bizarre issues with ffmpeg before, (especially the
3/27/2007 release leaking gobs of RAM during divx to mpeg encoding)
but that has not been an issue and doubtful would have anything to do
with whether mmx was enabled.

Oddly enough, I inspected the /etc/apt/sources.list and the line was
definitely there. But I worked
around that problem well enough by using apt-build, and the package
(revision 0.1 even though there is a 0.2 on marillat's site - it must
just not be available in lenny yet) is building. I set up apt-build to
build packages with -O3 and to tune it for my architecture (athlon
thunderbird) but only the -O3 seems to have taken effect, from what I
can see in the compiler output.
And I didn't yet get to add --enable-mmx so I guess I have to do that
again. How did you get around that issue? I'm somewhat inexperience
with building packages the debian way - and this is pretty much my
first time using apt-build. I've built plenty of packages by using
configure & make & make install, however.
IOW, I don't have Super Cow Powers :).
