Because if the game does it in hardware, MAME has to do it in code, and thus MAMEdev is on the hook for the MPEG license. If the game does it in software, MAME itself contains no MPEG specific material and we're clear (same way as Intel doesn't need an MPEG license even though a Core 2 Duo can run WinDVD).
