Just unboxed new ATV3 and tried running though Atlona 8x8 HD matrix switcher. Get sound but no picture. Tried connecting directly to TV and it works fine. Tried downgrading signal to 720p, still no picture through switcher. Apple says nothing they can do. Atlona: can sell me something to in-between the ATV3 and the matrix switcher that "might" work. Currently running TIVO's, DirecTv, Blue Ray DVD, iMac, iPad through switcher and they all work fine. Any thoughts?
