I have it, but I wouldn't recommend it. On the techical spec side of things, it looks decent on DX. But once you get it, you need to update things and tbh I found it to be a huge run-around. The companies that produced them were involved in legal battles at the time so, in turn, the consumer suffered for it. There's a general lack of help everywhere, and it's why the price on DX is so low. I said to myself, "naaaah. I have enough technical know-how to make the most out of it", but once i received my unit, i was very disappointed. But i had no-one to blame but myself! I don't mean to put the device down. but the lack of support and the type of system it runs on renders it unusable most of the time. I would look into other options.
I'm personally waiting on the GCW Zero, despite all the current setbacks. I still have faith in what I've seen.
Regarding video playback, It hasn't been the primary focus so far. I think maybe in the near future, they'll show off more of it.
