GPCinema vs MoviePark - I posted this on an earlier post :-
"GPcinema is way better than MoviePark" - don't be so sure.
Yes Gpcinema can supposedly handle higher framerates, although I've had MoviePark running at 25 fps (the problem is the sound synchro).
But MoviePark can handle Divx 4.12, RealMagic, 3IVX, XVID (any build), and ffvfw, and different frame sizes. GPcinema is very fussy about the codec and the frame size.
GPCinema (354 Kb) was not an upgrade of MoviePark (855Kb), but a totally new product , and I think it loses in flexibility.
