No, not so tall anymore. KDEnlive 0.7.8 runs much better than its
0.6-series for me. Not entirely flawless but perfectly usable for
productive work.

I also recommend Open Movie Editor if you want perfect Jack-integration
for a videoapp. Anyway, I would prefer to use KDEnlive for film-editing,
export a video, do the Audiostuff in Ardour synced to xjadeo playing
that video or synced to OME playing it.

 From my experience I suspect one of these problems:

1.) the ogv could be not very well supported and/or in a very high
resolution.
2.) you have certain effects running on the video (especially
color-correction modules gave me some trouble here...)

Both issues are related to very high system load. If there is really
something broken, we would not talk about stutter but about crashes/freezes.
