Try to unplug the HDMI and reset the settings..I think it says something about factory settings. Then Turn it off. Plug everything back in accordingly and restart, then start over as if the machine was brand new.

I played online with some friends the Night before launch, but ever since the NXE I can't join parties and can't voice chat Private or any other kind. I basically can't play anything online. It says there's a connection fail. So I tested my connection and it was strong. I used the same connection for 2 years now and played online without any mishaps. Now I can't join anything online without it failing and kicking me back. Anyone have any Info on this? Anyone had this happen to them?

Plus My Video quality is horrid for NETFLIX! I use the same Connection for my Computer and the Quality is great then I hook it to the Xbox and it s one big blur once the movie starts? Is there a setting I need to change or is something else? Any help would be appreciated.
