need a less taxing hq output from a cineform file?

[ade4all]

i need to project a 100" image of my film as a one off in a gallery space
my problem is i dont trust my dell studio 1737 studio core2duo 2.53ghz to play 30 minute 1920x1080 25p cineform file without occaisional stuttering. i will be using optoma hd65 projector which is 720p but seems to play 1080p footage sharper than native 720p. (not sure why)
i have tried using media player classic & windows media player & they have both stuttered about half way through the film
is there a good codec & setting within adobe media encoder which will output 1080p files with minimal loss of quality & be less taxing on my laptop - it plays 1080 & 720 mkv film files no problem but struggles with cineform
or is there a more efficient media player i can use to play the file?

Use h.264 with a high bitrate.

thanks for that, will try some different bit rates - been experimenting with different outputs but its a bit of a bind having to render then watch for half hour to see if it plays smooth, this will hopefullly speed things up
