I need nothing. You will need to prove your claims. I'f you can't it's your 
problem. I took a random video (with much panning) and surprise, surprise, 
GMC improved psnr nearly 0.1 dB. If you wan't to use a better metric or 
doubleblind viewing tests, I can send you the original video and both 
encoded versions. Where should I send them?

At least the public now is conviced that your prejudices against gmc, and 
the two other common mpeg4 codecs incorrect. You can flame as much as you 
want, but I ask you again to send those to my private email address because 
this list is about "MPlayer usage questions, feature requests, bug reports" 
and not about Rich Felker's private flames.
