I posted this in the main thrread but I thought I would post it here so everyone can see it.
I think I have a temporary solution for the black screen home button issue. This works for me for now so it might just be luck but I havent had it since trying this.
When finished with a game, instead of hitting the home button or saying XBOX GO HOME, say XBOX SNAP TV. This snaps my tv to the side, then say FULL SCREEN and now I am watching TV with no black screen problem. From there I have been able to hit the home button with no problem.
Hopefully this is a temporary fix until the patch comes out and hopefully it works and Im not just lucky the last few days of doing this.
