I recently authored a BD-R using DVD Architect 5.0. I have no problems playing it on my own Panasonic Bluray player, but it won't play at all on another Sony player - the BDP-S370. I tried burning on a Verbatim BD-R and I updated the player's firmware, but still no luck. The error message says something like 'This disc cannot play" and "Invalid" shows on the deck's display.

Any possible solutions as to why this doesn't work with such mainstream media?
