The kits and glasses are the technically the same and are designed by Bit Cauldron and merely rebadged. The difference in the kits is what is included.
The kit supplies an RF emitter to sync via RF with the glasses. The RF emitter (which John calls the dongle) has 2 cable connection inputs. The RF emitter dongle has to be powered via a micro USB to USB cable. In addition, to receive a sync signal, the RF emitter must also have either a separate IR receiver plugged in, or a direct VESA port cable connector for displays with these types of ports.
The MV kit supplies 4 cables with the RF emitter.
1) A USB to micro USB cable to power the emitter
2) An IR receiver to 3.5 that when plugged in, receives IR from a displays IR emitter and allows the dongle to translate it to an RF signal for the Bit Cauldron glasses
3) A VESA to 3.5 cable that allows the RF emitter to be connected directly to a display that has a VESA port for external emitters
4) An additional USB to micro USB cable for charging the glasses
The Optoma kit lacks #2.
#3 cannot be plugged directly into the Sony external emitter port.
John has figured the pinouts to the Sony port and is making a custom cable that can connect a Bit Cauldron RF emitter to it. Using this cable allows the Bit Cauldron RF emitter dongle to directly receive the Sony shutter glasses sync signal. Connecting this cable to the Sony port disables the built-in emitter exactly as it would if you plugged in a Sony external emitter.
For US users, the optimal option due to differences in pricing appears to be buying 1 MV kit plus as many additional Optoma glasses as needed since this route allows you to use the IR to RF conversion, which means you can use the Bit Cauldron glasses AND the Sony glasses simultaneously, if you wind up with more viewers than you have Bit Cauldron glasses for.
For our friends in Europe though, the MV kit and glasses are hard to get, so their options are to use John's cable, which means disabling the Sony glasses, or praying that AVS (or BHP photo?) will be willing to ship MV kits to Europe.
