Help with installation

Dear All,

For my tube site I need to install a number of applications but I don’t succeed. Is there please someone who want to help me?

The applications I need to install are:

Mencoder, Mplayer, flowplayer, FFmpeg, Yamdi, MediaInfo, x264 Library for Mencoder, GPAC MP4Box and neroAacEnc.

Is there somebody out here who has successfull experiences installing these applications and is willing to help me please? I can give you all accesses via PM when needed. Please this is really urgent. I need my site up and running as soon as possible or I will be in trouble.

Kind regards,
