[Andy Finch <we.rocked.in79@xxxxxxxxx>]

I'd be inclined to drop support for the older versions of MLT, or at least
make 0.6.2 the minimum required for the following reasons:


   - Users will get a better experience all round with newer versions of
   MLT.
   - From 0.6.0 onwards, the audio effects in Openshot were not working due
   to changes in MLT - our code was modified some time back to accomodate
   sox/MLT incompatabilities, which changed again in 0.6.0. Now they do work on
   0.6.0 and above, but probably wont work on anything earlier than that.
   - Kdenlive always specify a minimum MLT version (usually the latest) when
   they do a release, and they don't seem to get too many complaints about
   that.
   - One of the reasons for removing melt initially were that some
   non-Ubuntu distributions were apparently not going to ship melt (I don't
   have any confirmation of this).

So long as we make it clear what versions are required and give some good
instructions on how to obtain a later version of MLT (i.e. from a PPA) then
I think we can get away with setting 0.6.2 as the minimum. I don't know
what's involved, but could we feasibly include a package of MLT in our PPA?

Andy.
