A few days ago out of total frustration, I deleted everything of my xbox.. No games, apps, 0% memory used and reset to factory settings, and cranked it back up. Lag is still there but significantly lower. Ya!!! Been playing with the lag issue so long that I could somewhat predict when someone will land that had been suspended in midair a second ago. Now I find myself ... over compensating so now I guess I have to learn to play with less lag now. Still going to get that ethernet cable for a direct hook-up and hope that it clears up everything.
