dakujem za pomoc.

da sa to oklamat cez hex-editor, viac tu: http://www.ode2.com/?p=12
(trik nebude fungovat, pokial dany video subor potrebuje na prehratie dany level, na ktory je nastaveny.. (ale myslim ze by to nemalo robit problemy.. co som tak zbezne pozeral tak na fullHD staci aj 4.1))

raz som nasiel na to soft, prepisovalo to hlavicku a este par veci...no vysledok sa kockavel, sekal a nebolo to pozeratelne, lebo prehravac k tomu podla takto modifikovaneho nastavenia pristupoval inac, ako mal.
Zbytocne riesit, fungovat to nebude.
