1. Beamer
A connection to a projector via HDMI is impeccable possible. For me it is the Acer P1500.
2. Amazon Instant
There are two different versions of the player:
1. An "old, broken" version. Here the Amazon Instant app is not (!) On the player, but the player also already contains the latest software version. The app can not be put on the player.
2. The second, the "correct" version. This is right in the Amazon Instant App. A software update is possible, but this does not change the Appauswahl (thankfully).
Other differences between the players does not exist.
How do I know that? Internet research, talking with retail employees and also I have two of these BDP before me, once the version 1 and version once. 2
