just thought i would see if anyone could help

ive downloaded the planet earth in 1080p(48gb)

the only program that will play it is VLC media player, the only problem is it keeps stuttering or pixalating, the audio is fine but every few seconds the video goes wonky

i was wondering if there are any other programs i could use instead or anything that can help

im running 2gb of ram and 2.8ghz AMD processor so im not sure if ive not got enough power


any help, links or suggestions are welcome!!
