Sync works, but streaming just stopped

Question

Up until recently, I could sync and stream from iTunes to my ATV, no problem. Movies that I had in iTunes that were not synced would stream. Now, I can still sync, but nothing is streaming and I have not changed any settings.
I am using a custom sync, but I have not checked the "Show only the synced items on my Apple TV" option. My ATV is 2.3.1. Here is my iTunes diagnostic log:

Any chance you've inadvertently unchecked the tick box next to these items in the main part of the library (not in AppleTV device tab) ? If so they're excluded from streaming - prevents certain content you migt not want to stream appearing.
No. I just double checked.
Nothing is streaming, but I can sync okay.
