I don't know why, but CPU run at 100% since I installed it yesterday

half is used by mezzmo.exe and other half is used by ffmpeg.exe

is there a reason for that?

And on the mezzmo state area I see: system task, extracting video, 1307 left (I use the french version so I have translated it)and it as been like that for an entire day.

My hardware is:
Socket 939 AMD Opteron 148
2gb of ram (DDR-400)
3x640gb for multimedia storage
Windows XP64 with latest updates.
