LG BD570 Network Blu-ray Disc Player

First let me state that I do nothing (I'll use the term) exotic with the player such as attempting to play self created MKV files (whatever those are) or avi files or connect an HD to the player. My 570 player came defaulted to the 60 Hz format vice 24 and it is connected directly to the TV using HDMI and I've experienced zero problems playing Blu-ray disks. Some have reported problems when the player is set to 24 Hz but changing the player to 60 Hz seems to correct those issues. For the record I own, and am delighted with, an LG BD390 which I've owned for some 15 months or so. I've owned the BD570 for about 8 weeks now and the only hiccup I've had with it whatsoever was getting Vudu activated on the BD570 and a two minute telephone call to Vudu corrected that issue. I've played a number of Blu-ray DVDs as well as SD format DVDs and have not experienced problems and I judge the 570's ability to upscale SD format disks to something approach HD as being very good. I will note however that I've not tried the Blu-ray movies "Up" or "Terminator Salvation" which according to some reports give the player a problem. We have streamed numerous Netflix movies and we've not even experienced any buffering - although I did experience that happen on the 390 once with an HDX formatted movie. We've not streamed a lot of movies from Vudu but the few that we have I've not experienced any buffering over a wireless network from Verizon's FiOS 25/15 service. In summary we are delighted with the 570 and I see no difference in picture quality between it and the 390 and it streams just like the 390. Other than the much smaller footprint and the menu system being somewhat expanded on the 570 the two players seem essentially identical for my purposes. I think both the 390 and the 570 are quality products.
