A little background - I've tested every single hybrid iptv box available. I received my buzz tv as a test unit from my supplier. I typically sell dreamlink T1 but will be stocking the Buzz next week. My supplier is also giving me a T1 Plus for testing so I will have some info to share on that device as well.
red = lock channel
green = last channel
yellow = add fav
red = VOD
I do not post videos of my testing. No group button required.. channel categories appear on the left side and as you hover over the folder you see the channels listed to the right. While hovering over a particular channel you will see a short 5 hour EPG. (Check out the avov videos on youtube to get an idea).
I haven't come across a user forum or any mention of this device on any of the forums I frequent (this box is relatively unknown at the moment).
This box has only been out a couple weeks and has only had one update so far, however, that update did fix the only glitch that I've found. I prefer the dreamlink EPG grid interface to the buzz TV's grid interface, not that I use that feature much. Navigating the box is much quicker and seamless on the buzztv, for example, switching between servers is very quick as well as one button switching between kodi and live tv.
**They absolutely need to integrate the EPG single view that the dreamlink T1 has in order to take advantage of tv-catch up auto-PVR function that some servers have. That is the only major functionality missing from this device at the moment. But then again, this only matters if you happen to be on one of the few servers that offer this type of function.
