It basically becomes a question as to whether the functionality belongs in 
Kdenlive or not. The original design spec was that Kdenlive would perform no 
video editing itself, and would only perform video tasks via some separate 
renderer (i.e. piave). This is analogous to your own GUI - the gui is purely 
a frontend for the underlying renderer, albeit it needs to be a fairly 
sophisticated one.

I would prefer to keep this as much as possible - so if we need to render to 
mpeg 2, I am quite happy for that to be done via transcode... but it should 
be done through a piave plugin. As for loading mpeg 2, I think that a 
transcoder-based gui converter that could do mpeg-2 to dv and dv to mpeg-2 
would be so much more useful at least in the short term, since it could be 
used by anyone, not just by kdenlive folks. In the long term, we can then 
stick to the "correct" plan and implement mpeg2 editing in piave :-)

Cheers,
Jason
