I got them about a month ago from alt.bin.x264 - They are great quality. Play perfect on my setup. Not sure why but some 1080p movies are choppy. Got the Spiderman Trilogy. They run like shit. Here are my specs:
Core2Duo 2.2 (no idea which model)
2gb ram (Corsair DDR2 cas4)
EVGA Nvidia 8600-GT 256MB
3x 1TB Seagate SATA drives
Vista Ult. running MCE
I have one of the HD's dedicated to HD movies. It's already half full. Just got the video card after reading that it has x264 hardware excelaration. Runs almost all movies with cpu usage around 30/40% but spiderman is still choppy and lags. I'm running the powerDVD x264 codec since it's the only one I know of that supports the hardware x264. Would love to figure out how to get this working better.
