Kino problem: Playback speed when making changes

Thank you Dan, for inviting me to ask my question. Here it comes:

I am using Kino under Ubuntu Studio 10.04 and whenever I try to make any 
changes on my movies or even just try to play a movie from somewhere in 
the middle, when I click on "play" the playback speed is way too high.

If I save changes then and restart Kino, I can play the movie back 
normally again - but only from the beginning. If I start from somewhere 
in the middle, the playback speed is too high again.

I would highly appreciate any ideas/suggestions.

Thanks,

Johannes
