Just received my 103 today, and have been playing with it this evening - I have over 400 titles (THAT I OWN) ripped onto a Synology server, so I wanted to test this first.
So the mostly good news is that it's playing the Blu Ray rips great - select a folder, hit enter, and it plays. I did have an issue with some branching Blu Rays, where it would just hang on a black screen after launching, like the Alien's Anthology and the Avatar Special Edition set - but I re-ripped with the latest AnyDVD HD, and now they play correctly (presents the title screen to selection which version you wish to play). I can even play a 3D BDMV from the NAS and it works (most of my 3D rips are to ISO, so I will have to redo them as BDMV's, which AnyDVD warns is not ideal, but i'm not sure why and if it works, I won't care)
What I can't yet do is play a DVD rip - selecting the folder only opens the folder, revealing the VIDEO_TS folder, and clicking that shows the VOB files - I can play them individually, but there is no coherent way I've seen yet to play the folder as a logical title.
I played a few m4v files authored from Final Cut Pro of my home vacation movies, and that seems to work great as well...
So by and large, really quite pleased - and I haven't opened the tray yet!
Extremely well built machine, the video and audio quality are superb out of box - 23.98hz material plays very smooth, switches to 59.94 correctly as well on everything I've tested.
There is a known bug (called Oppo) where the network file folders are not listed in correct alphabetical order, so hoping that will be fixed in the next firmware in a few weeks.
I also discovered it's pronounced OH-PO, not AH-PO, though this has not materially changed my life.
