So, I received my 600X3D yesterday to replace my A-400. I gotta say, wow, talk about night & day.

Literally every file I could not even begin to play on the A-400, I had absolutely no trouble with on the 600X3D. Not only that, the UI is *much* snappier, especially during playback. It does feel a bit less polished, though, overall - compared to what I've used before. However, I'll reserve judgment until after 2.0.
Currently, I'm running an alternative install of SMB 4 on OS X Mountain Lion, with a couple socket tweaks in smb.conf. It was interesting to read all the advice about using NFS to improve performance. So far, with SMB, I have zero trouble with even the highest bitrate 3D ISOs.
A couple issues:
- I can't seem to find a way of sorting the file list view in a network share, it would be most helpful if this remained in ordered by creation date descending as I generally always want to see what has been newly added.
- The lack of HD audio out of optical is a huge pain since my AVR supports DTS-HD and True-HD but is HDMI 1.3a. :\ I ordered a 1.4a HDMI splitter, hoping this does the trick.
I also can't seem to find a way in the UI to monitor current bitrate during playback. Is this possible?
