I don’t know how many people here are using 7 for media center purposes, but I started having problems the other month with some kind of jitter problem with TV and recordings. Looking on thegreenbutton it seems there are a lot of people with similar issues. Everyone has theories, but no one can pinpoint a specific issue. Some say it’s an Aero issue, some say it’s an ATI issue, others the decoder, some even say it’s something to do with Homegroup and IPv6 (or something like that). The point is, something’s definitely going on and not a very good start for 7 that’s not supposed to “have any of the issues that Vista did”. Guess they’re right; this seems to be a new issue all together.
