All good points. =)  I think we should definitely consider getting MLT into
our PPA.  My only concern about including MLT, is this feeling that by
installing our PPA, it automatically flags MLT to be updated to our version,
which will likely break Kdenlive.  Remember back to TJ and some of the
issues we had with his packaging and PPAs.  All of a sudden, apps like VLC
no longer worked, and they blamed our PPA.

Just a thought:  We could add the "melt" based methods back in (and the melt
executable preference), in addition to the new code.  Maybe, use the old
methods as a "fallback", if an older version of MLT is used.  We could also
disable audio filters for older versions of MLT, prior to 0.6.0.  Just a few
tweaks to the code in question, and we could support Ubuntu 10.04 to Ubuntu
11.10 (4 releases).  All of this will disappear when we switch to our new
video editing library.  I can't wait for that day to come. =)

My feeling is that once the "melt" issue and packaging issues are resolved,
there is not much more that will break on Ubuntu 10.04+, unless some pyGTK
stuff breaks.

What do you think?

Thanks!
