Spent some time today playing with DLNA. Overall it works... but can be problematic. The best program I've found for Android is one I purchased about a year ago called BubbleUPnP (see pics). Overall, this is the best all-around UPnP server, player, control point I found after dismissing more than a few. I also use it as a DLNA server at work to listen to music on my BMP. All round a good performer. The pics above give you an idea what to expect using it to control the BDP-105.
I also tryed the Linn Kinsky controller, but just don't like the rooms orientation as I'm only listening in one room. YMMV.
I'm going to refrain from a "how does it sound" review right now as I only did casual listening while focusing on remote controlling the BDP-105. Mostly I listened through my so-so headphones: Grado SR80s and AKG K550s. As you can imagine, there was no problem driving these phones as they are designed for portable listening.
So, DLNA control, one of my top must haves works, but does have a serious flaw with the UMS server. The issue is a song in the play list stops playing abruptly. By stops playing, I mean that the Oppo counter is still counting, the controller counter is still counting, but there is silence
The counters continues, and appears to go to the next song, but more nothing is played. If I tap on the next song in the play list, it will play for another 20 minutes or so before it happens again. Seems to happen near the end of a song, so probably related to the change to the next song.
The Oppo is connected to the same gigEth wired network as my BDP-83SE, which has never failed to play a song all the way through. The NAS and network are loafing. Am trying my other server, Asset UPnP to see if there is a compatibility issue. Been playing for about 45 minutes so far with no issues
On the plus side, the BDP-105 plays many, many more file types and containers than the 83se. On the down-side, I can no longer even listen to my blue-ray or dvd concert discs as I've got an old LED TV with a composite and a D-Sub connection. Now I can listen to the ones I've ripped to disc, but still no video at all.
Update 12/25/2012: The issue with the deck failing to play a song all the way through has not happened since I settled in on Asset UPnP & BubbleUPnP. Many, many happy hours of listening to music
However, I do still need to reboot the 105 occasionally for it to be fully network operational, sometimes twice in a row. Never had to do this with the 83SE, so me thinks there are still some warts in the 105 DLNA render implementation.
