Cannot upgrade from sunab ppa (Ubuntu 10.04)

Per instructions on the download page at kdenlive.org, I added sunab's ppa to my software sources and tried to upgrade using:

sudo apt-get update
sudo apt-get install kdenlive

The result? Package dependency hell.

Please advise. I'm having trouble importing long audio files, but by forum policy, I won't be able to ask those questions until completing an upgrade... which I completely understand, just want to make sure I'm doing things right.

really what you should have done first is completely removed all things like FFMPEG, melt, kdenlive, ffmpeg libraries. Then added his repo, done an update, then done an install of Kdenlive. I am using Sunab's ppa for ubuntu 10.04 along with medibuntu lucid-staging repo for the ffmpeg libraries. I can render to mp4 which is h264/acc codec. Good luck
