"jumping" titles (animated titles) - sometimes jumpy, some time smooth (as it should be)

Hi
(don't know if posting the right place)

I've made this trailer to a game.movie, with some scroling titles, but they seem to jump like an old B/W movie ;-)

is this caused by Kdenlive or mlt ? .. or ?
Just trying to figure out, where/how the problem originates..

have posted the movie (trailer-part) here :

OS Suse 11.4
Kdenlive v. 0.8.2
Mlt 0.7.6-1.5

Could you elaborate on how you created this title? Perhaps a screen shot of the title in the timeline will help.

sure.. but it's just put in "like any other clip" ..
