I'm not absolutely certain, but with the BDP-83, it might be a simple matter of it being limited to the FAT32 files system and as a result can't read the relatively large 15gig file. This is true of most BD players. The 93/103 can support the NTSF system, I believe, which can handle files of that size.

Yep - the 93 supports NTSF (I have one,) my Brother In Law's 83 only supports FAT32 so it doesn't even see the file when I try to play if from a thumb drive in his machine.

I find it odd that his 83 is having trouble with it. How are you playing it on the 83? Did you burn it to a BD in an MKV container? How would the 83 have issues specifically with H.264? Isn't one of the most common BD codec standards (that virtually all current retail releases utilize after they stopped using MPEG 2 and VC-1)?

Is this:

What you're talking about? That seems like it's more of an issue with Handbrake and less of one with the 83.
