060 real time speed

68040 does 1.1 MIPS per clock, 68060 does 1.33.
A person also has to take into account that the '060 runs at a higher clock rate, plus its superscalar architecture. a 50mhz '060 is probably on average 1.5 times the speed of a 40mhz '040, but on occasion it's closr to 2x the speed. While higher clocked '060's are faster they dont scale well in some situations due to ram bandwidth being a bottleneck.
 
The difference is definately noticable, although dvd playback is still too much for an '060, especially when using aga.

The FMV module contains an mpeg decoder chip, which is why it plays reasonable quality video.
As for playing videos on a classic amiga, I understand the appeal even if its not practical. It's quite fun, if tedious at times to convert videos to a format an upgraded amiga can cope ok with. DVD unfortunately just isnt one of those formats.
