[PD] GEM question: reading from big videos

I have almost no experience with GEM, so I wanted to ask around about
this. I have a patch that should play 3 HD films, in the following way:
- the main patch plays the sound, and sends the frame-infos around through
- the frame-infos are received by 3 video player patches (each in one
separate Pd instance), each one playing one film
- the films are a bit heavy: 1/3 full HD = 640x1080pix each, around 6m
long (maybe more). The playing speed is around 25fps, sometimes less,
- the hardware has a SSD disk, and i5 quad processor > 2,7Ghz (I can't say
yet much about the graphic card)
Which object is more adequate to play these videos in GEM?
Probably isn't a good idea to load the videos into RAM. The playback is
also very variable: forward, backward, something else... That means, is
there a buffer-setting that would help in this case?
And, under this context, how fast could the video be played?
