My BD-390 just arrived today and I wasted no time in setting it up. I have a wireless router, so I tried that first. I use WEP2 encryption and when it came time to enter the password into the 390 there was no way to enter capital letters. The manual said nothing about how to do that either. I gave up and plugged in a wire stolen from another device nearby. Now I'll have to get a network switch to allow both to work at the same time.
The audio setup was next. I have an old Yamaha DSP-A1 that does not have HDMI inputs, so I connected it via a Toslink cable. I configured the audio settings to convert to DTS over SPDF but when I used the internal Test mechanism the back speakers and subwoofer did not emit sound. No combination of settings allowed the test to be successful. Sound only came out of the left, right, and center.
Playing a Blu-Ray disc worked flawlessly, and the sound was correctly down converted to DTS and all 6 speakers worked. Same thing for a DVD with Dolby Digital, all speakers worked. So the player audio test was a false negative.
Hooking up to Netflix was an excellent experience. Just select Netflix on the player, and it displays a code. Type that code into a browser that is pointing at the Netflix website and the player and Netflix auto sync, and my instant play list appeared, instantly.
Next was the DLNA feature, one the main reasons I got the 390. The Nero software included installed easily on my XP computer, and the 390 had no trouble finding it and showing the shared folder I had configured. I tried a few mp4 movies I had, no go. Snurfling thru the manual I see that the 390 only supports mpeg2. I like to create slideshow movies of travel photos, and I usually make them in mpg4, but the Pinnacle software also can output mpeg2, so that's ok.
Next test is an official movie night with Quatum of Solace. Not sure if I will see an improvement over my HD DVD player, especially on my 720p DLP TV, but all the other features make it worth the upgrade.
