What do you think about putting this script into the main trunk?
I have a Turion 64 x2 TL-56 laptop and it seemed too slow or dated to play 1980x1080 content, until I used ffmpeg-mt builds of mplayer, now they play just fine. With dual or quad core processors being the norm, they are no good if the software isn't designed for it.
Even with an additional 2 mplayer.exe binaries for AMD and Intel that are 31MB, it compresses well and adds just 4MB to the installer size.
There seems to be some issue with mpeg2 decoder w/ # of threads set to higher than 1, maybe some exception can be made for mpeg2 so that it will use only 1 thread.
