This is a really new beginners question, since I just installed Kdenlive (much thanks to what I read on this site).
The first thing I wanted to try was to edit an avi-film (that was originally captured with MS Moviemaker). To my big surprise the program don't seem to find the avi file at all. I therefore tried to browse to the file an choose open with Kdenlive... but I only got this error message "error occurred while parsing element"
So what is wrong? I testet with Kino and everything worked perfectly, but from what I've seen I'd rather work with Kdenlive than Kino.
I'm using Ubuntu 9.04 Jaunty and installed Kdenlive from “Add/remove..” and it's version 0.73
Probably I just missed something basic, but I can't find out what it is. I've been searching around but can't find that any other new beginner got this kind of problems.

Thanks for your reply.
Here's the deal. I have all of the packages installed according to Synaptic – but not the unstripped versions. Does this matter? Since I'm pretty new in the Linux world I get a bit nervous when Ubuntu pretty much tells me that I'm going to install an unrestricted package and that the other one is to be removed.
No danger in proceeding?
