HELP! HELP! HELP!

What is different between episodes 1 and 3 versus 2 and 4? I am trying to play these episodes on an ASUS O!Play HDP-R1 media player with firmware rev 1.33N. Episodes 1 and 3 play fine, but 2 and 4 have sound but no video. The fact that two of the four episodes play perfectly indicates that there must be some difference in your production process between the episodes. Anything information you can provide would be appreciated, so I can advise ASUS of the problem. I have downloaded the 720p H264 version - I don't know if you have any other resolution available.
