it's not 2 GB - it's 2.15 GB exactly. This was a classic problem with Adobe as well (at one time) where you could not record out to any network volume with Apple computers that was over 2.15 GB. This was well documented, and can still be found if you google search around (something like cannot record files greater than 2.15 GB with Adobe Premiere or Adobe After Effects). Apple was never going to do anything about it, but Adobe did - Adobe fixed this issue (I think back with CS 5.5 or CS6) and there is no issue with Adobe software to any network volume now (and your QNAP TS-1685 is a wonderful product). The fix was posted by Todd Kopriva, who is the product manager for professional video software at Adobe. And there never was an issue with FCP 6, FCP 7, FCP X or Media Composer either. At the time of the problem, I would simply install FCP 7 on people's systems, and tell them not to use Blackmagic Media Express, and to capture with FCP 7.
SO - Blackmagic never addressed this issue, and the only way to record to a network volume with Media Express over 2.15 GB is to a local drive connected to your Mac, and then transfer this (drag it) over to the QNAP. This is NOT a QNAP issue - this is a Media Express issue, that I guess, Blackmagic feels is too unimportant to address. Let me be very clear about this. If you had your Mac running Blackmagic Media Express, and used simple file sharing to mount another Mac with a USB or Thunderbolt drive to your Mac, so you could record your video (using Media Express) over the network (over a simple 1G Ethernet cable from Mac 1 to Mac 2) - this would FAIL at 2.15 GB (when using Media Express). When is this being "fixed"? If I were you, I would not hold my breath.
