I had rendered my latest project from my NLE to an mpeg2 1280x720, 30mbps file for a presentation. The rendered file runs fine and smooth on my main workstation. But the file stutters and runs in slow mo with audio dragged out on the presentation system. Both systems are dual core and with 4 gb ram each. Seperate media HDDs etc. Task manager reports CPU usage is just 10 to 20% when its struggling trying to play the file. So i dont think its a system bottleneck.
Is there a recommended and reliable codec pack that allows us to play the above mentioned file please ?
