Mine is also not DoA. Works fine both normal recording and PC Free recording. Only problem is that my monoprice splitter (mini-HDMI 1x2) does not interact with it well. It causes the recordings during PC Free recording to be sped up and high pitched. It's a little weird, considering that, normal recording mode is fine and without this problem.
My Transdcend 64GB SDXC works fine with the unit as well. I just had to format it using guiformat to fat32 with 32k size allocation units. I am fine with RECentral. Main advantage is that I don't have to see a preview window if I don't want to and eliminate any dips in performance.
I still need to test if any other mini USB cables work with it and if it can be powered by a USB power adapter.
I also bought one of those ebay HDMI splitters and will report how it interacts with the LGP.
My only wish is that it could do 1080p60, but then again, that could be based on the hardware limitations. But if it can be unlocked via software, I'd definitely be all for it.
Also, their support is now reduced to posting on either Facebook or Twitter and hoping they respond to you. Their forums have been down for months it seems. So if you do have a defective product or have a problem, I would suggest returning the item instead of trying to deal with Avermedia.
All in all, like BPA said, if it works, then it is the best capture solution out there.
edit: My other monoprice generic mini USB cable works with it.
