It is for playing avi files etc.  Thing is I don't have windows but do
watch a lot of avi files.  Its a pity, the reason I chose Ubuntu was

! scropped between Cpu(s) and Cpu0.  They do seem to be showing
different info.  Is This correct?

I too am a fan of gkrellm.  Running it does not seem to show multiple
