Hi. Youtube has choppy playback for hd on my vista 64 machine, dunno if this has much to do with the codecs that I have installed. My xp machine does not and its a much lower spec. My main problem is playing back large 1080p MKV files. It used to be fine? I have tried uninstalling all my codecs but i think some still remain. Codecs i have tried, k-lite basic - full. K-lite vista64. Vista codecs pack plus 64bit content. Core pro codecs. I've tried mixing them and on their own. Problems still persist. I also have VLC (which i think installs its own codecs), premiere cs3 and pinnacle studio 11. I have no idea if these programs would cause issues. My specs are: Vista64 Premium. Intel Duo core 2 E6700. 2.66ghz. 4 Gig ram. 2 terrabite harddisks runnning in raid 0. 8800GTX with latest drivers. Audigy 2 ZS platinum sound card with latest drivers. Here is a text printout of my codecs from the program G-spot: ยค Video AVI Decompressor {CF49D4E0-1115-11CE-B03A-0020AF0BA770} 0x00600000 quartz.dll - ACM FmtTag: 0x0011 IMA ADPCM CODEC for MSACM
