I looked at the Boxee Box but it failed all of my basic tests (from what I can tell; D-link does not seem to provide complete specs anywhere):
No gigabit ethernet.
Irrelevant to Blu-ray streaming 100Mbps ethernet is more than enough.
No indicated menu support in ISOs (although this is becoming less important to me now that I'm switching everything to MKVs.)
Correct it has no BD menu support only DVD.
No Samba or NFS serving of connected storage.
It does support serving attached USB HDD's via Samba.
What specs they do provide seem to indicate no DTS-HD MA support and no MPEG2 in MKV support. Of course, it is possible it has all of these features and they are just not documented.
With these boxes I guess you don't know for sure until you try it. I was thinking of trying the new Popcorn Hour A300 next, but maybe I'll have to give the Boxee Box another look since it is available in local stores and is easily returnable.
It does support MPEG2 in MKV and has DTS-MA pass-through support, the Boxee Box has the best codec support of any player on the market as it stems from a PC application. However in the current firmware there is a bug affecting TrueHD/DTS-MA which causes audio dropouts, a fix is in development and rumoured to be coming in the next major firmware update.
The Popcornhour A300 and Popbox V8 do not support LPCM in MKV at this time but they are going to fix this in a future firmware update, they both do support BD subtitles in MKV. The A300 also has unofficial BD menu support but how long that lasts is anyone's guess.
Thanks for the feedback on the Boxee Box and the A300. Good info. Although if the Boxee can't decode DTS-HD MA, then that is probably a deal breaker.
I'm going to disagree on the gigabit ethernet being "irrelevant" to streaming Blu-rays. The real world throughput of 100Mbps ethernet and the max bitrates possible with Blu-ray are far too close in my experience and in fact sometimes cross. I have examples of both feeding off of the same server and can certainly see that the extra headroom afforded by the fully gigabit path is necessary for my investment comfort. I agree that 100Mbps with decent buffering is generally going to get the job done, but I like that extra headroom so that there is one less link in the chain to wonder about when troubleshooting. Plus, my media players all also act as servers so the faster transfer rate is also a plus in that respect.
The A300 is still looking like the top candidate, but my NeoTV 550 and my uebo m400 are so, so close that hopefully the next round of firmware updates (if they arrive) will obviate the need for the next player for a while. The 550 just has the tiniest bit of playback issues with some of my mkvs (visually it looks like just the occasional, random dropped frame; although on one occasion, the failure was much more dramatic) and is also not quite there on the attached storage server performance. The m400 really just needs the subtitle support. The video and audio playback has been flawless so far. Also, the m400 has a fan that is a bit too noisy. I'm going to take a look and see if the fan can be easily and safely disabled on the hopes that it is really there for the case where an internal hard drive is installed (mine will all be external.) The BD menu support has also been a failure on the m400 thus far, but as I said, that is becoming less and less of an issue (but would be nice for my homemade BDs.)
