I see... But what about 1.85? It usually would have small black bars when watched on a 1.78 projector. They're usually not seen since most of them overscan and therefore hide them. But with an HTPC you can get 1:1 mapping and the black bars would show up (I did see them when I tried playing some DVDs on the Z2 with my Linux box). Do you see some with TheaterTek?
