I upgraded to V3 after the snag was ironed out. This version is as reliable (maybe more) than the prior version. The picture quality is very good when fed a good quality file. Frankly the UI, and ease of drag and drop list re-org and additions make this a true “Mac” Application. The UI’s feedback is great and snappy. It works fine with the Apple Remotes, and scrubbing back and forth is accurate as well. On my 802.11AC network (even though the laptop has only 802.11N), reload times after scrubbing are fast enough to avoid that annoying delay one gets when streaming Netflix or Hulu when you jog back a few seconds.
About the only thing that would make Beamer better is if it could be launched from the 4th Gen AppleTV via a tvOS app, and load a preset folder to chose videos from so you could leave the computer locked or alone. But this “wish list/bonus” feature would probably a v3.5 or v4 feature, or maybe a $2–5 tvOS companion app?
I occasionally get dropouts where the App disconnects from the device or it initially can’t access the device until I reboot my 4th Gen AppleTV or the laptop, but this happens across all streaming from both the net and my computer, and even my Bluetooth Gamepad controller has problems initially connecting sometimes. (This I blame on xOS 9’s & OS X 10.10+ known problematic network stack.)
So, I can’t ding a developer for flakey network reliability of the AppleTV, nor the occasional 2.4gHz band noise spikes in my area (which seem mostly responsible for the disconnects). In case you’re wondering: I have a good 802.11AC router with beam forming going through 2.25* walls and a noise floor below ~-80dbm with average RSSI of <-60 (-54 to -58). So noise spikes can sometimes drop it below the ~12dbm S:N it seems to require to prevent dropouts. (I’ll probably mount the router in a better place if noise increases in my area & I get knocked off more frequently—that or go back to the 90s Ethernet setup I had a few residences ago.)
* the .25 means one “wall” is a cabinet wall less than half the thickness of a wall.
