great tool, but no binary in rpm format, and I really can't install all
those ****-devel rpms in order to compile a gnome application.

I would like to reduce the file size but keeping the video quality.

Those Southpark MPEGs are 352 x 240, are you suggesting I scale down to
320*240? I will make yet another test :)

The vhq option has been taken away from the lavcopts section (in man mencoder)
and replaced by the mbd=(0,1,2) or that's my understanding of it.

hhmm, and I thought I could use just one script for everything :(

Thanks for your reply!
