VLC stopping playback when jumping to timestamps for media on SMB share

Well this is odd:

SHA1 hashes of a particular test file locally on both boxes match.
Copying to my local machine from both boxes, and for the old box the hash matches local, but for the one from the new box the hash is different.
Hashing over the network, old box matches local, but I keep getting unexpected network exception when hashing the new box.

Old Local  		 - b99505ed63a84659e25209b1b7420f03e2541a7d
New Local 		 - b99505ed63a84659e25209b1b7420f03e2541a7d
Old client copy  - B99505ED63A84659E25209B1B7420F03E2541A7D
New client copy  - 55A4B2D22B3424845EE7DFCFDB8F7066E4F29168
Old network		 - B99505ED63A84659E25209B1B7420F03E2541A7D
New network		 - Fails

Given I used the same adapter to complete the replication originally, and via SMB, I’m confused why when reading it back from SMB the hash would be different? Especially when locally the hash looks to match?
