Just received my second BD390s today (one for upstairs and one for my theater downstairs). I do not have a hardwired Internet connection downstairs so everything downstairs connects to the net via a D-Link DAP 1522 wireless bridge which picks up the signal from my D-Link Extreme N Duo Dir 855 wired/wireless router located upstairs.
Here's the setup: The downstairs BD390 connects to a D-Link Gigabit DGS 2208 8 port switch which in turn connects to the D-Link DAP 1522 wireless bridge. The BD390 is connected to a Denon NR905 via HDMI, the Denon is connect via HDMI to a Monoprice 4x4 HDMI Matrix switch with one HDMI out going to my RS1 and another HDMI out going to a 24 inch wide screen monitor that's in the downstairs bathroom (don't want to miss anything when you have to go
Picture was excellent from the projector and also on the bathroom monitor. I watched several Youtube videos full screen with no stutter or glitches.
Selecting "My Media" I watched 10 to 15 minutes of several movies, located on a computer upstairs, that were in different formats: .avi, .vob, & .mkv. All played flawlessly.
Next I checked out Netflix which indicated 7 bars and watched 30 minutes of a movie without any delays, stutters or glitches. After that I tried Vudu, selected "New Trailers" HDX and watched trailers for about 30 minutes without any stutters, glitches or delay. The trailers loaded quickly; the HDX showed only 1 green bar.
After the trailers I settled back with the .99 cent movie of the day "Hellboy" in HDX. The complete movie played in 5.1 without any stuttering, buffering, glitches or delays.
Although there are still some areas that need addressing (can't get subtitles from mkv or vob files) I'm a happy camper.
