playing HD videos on my mac

[gelatin]

i have an 14" ibook g4 1.33ghz 1.25gb ram

what factor is stopping my mac from playing hd videos such as the gta 4 trailer smoothly?

the file is 1280x720 pixels and file size is only 125mb

the GPU although I thought they came with a 128mb card....it should play correctly granted you have installed all the correct codecs

I'm sorry I thought you had a PB g4 (weird they don't have 14" PB lol) yeah it's definitely your video card...
