Video playback is jerky

sounds like the spikes at startup are caused by one of these:

-system restore
-indexing service
-superfetch
-readyboost(probably not)

system restore is easy to turn off if you want to do a test, but I don't think you can really turn off superfetch, nor should you.

I'd say the best solution is, don't shut down or restart your system! That way instead of waiting 45 minutes, you'll be ready to go in 45 seconds or less.

Properly configured for S3 sleep you computer won't really use any more electricity when sleeping that it would if turned off (maybe 1 watt). If you are worried about power outages you can use hybrid sleep or just use hibernation.

Of course it is possible that certain tasks will still run in the morning when you wake up the machine but it's worth a try, and in any case S3 is great. I stopped shutting down all my machines years ago, except my laptop which I often hibernate.

I thought this thread had died since I started it a year ago.
What finally cured my problem was installing K-Lite Mega Codec Pack135.
That is a really OLD pack. I use it in XP. I've never had any problems with it so I never upgraded it. I doubted if it would install in Windows 7 but it did and I've never had a problem with the stuttering video since. I posted this in the Sage TV forum and they canceled the post because the K-Lite codec is supposedly illegal. It's readily available and I've really heard very little about its legality. If it ain't legal, then where WOuld I go to get a codec that works like it does?

I fixed mine by changing refresh rate from 50 to 60 hz

I, as many others have, upgraded from Vista 32 to Win7 64. I did have installed K-Lite Video Pak Full, and no problems. Then, out of nowhere, the jerkiness started...even moving my browser around was jerky...THEN, I read in this thread that a reinstall of a 64 bit version may help. Well, Voila'...it worked. Just wanted to pass this on. And yes, I too had little problem with my Vista. In the end, after all the fixes by MS, it worked fine...but oh-no...I HAD to upgrade cause I was given a disc. Anyhow, all is well, and I went thru the intense registration to share this.
