Have you received a response to your question regarding simultaneous record/playback for the HyperDeck Studio Pro?
I work for a church with multiple venues but only one live sermon location, and yes, it would be very helpful to have a product at this price point that could simultaneously record and play back a sermon that is still being given.
The HyperDeck advert in Technologies for Worship magazine says that it can do "instant replays' for sports production but what does this mean?? It should mean that the sports event is still being recorded but that you can go back and play the spectacular goal without missing the possible playback of the ensuing celebration. But BlackMagic, in my view, is trying to project a "Simple but professional" image for it's products (or they are too lazy to write out long spec sheets that actually tell you all the formats and the ins and outs of their products or how to actually use them). Alas, I am an amateur in the video world and perhaps that is the problem.
