I've had the LG BD670 for less than a day, so take my limited experience for what it's worth 🙂 I bought this mainly to play video content over my home network without having to plug in a USB HD.
I also have a recently-purchased Sony BDP S580 BD player that I'm testing and figuring out which to keep.
I installed TVMOBiLi (a DLNA server) on my early 2008 MacBook Pro (core2duo) (OS 10.7.2), and after an update to the latest (beta) version of TVMOBiLi and a couple of restarts, was able to get it to work.
The LG BD670 is able to see folders that I'd set up to share. Also, if you press the Red 'R' button on the LG remote, you can change the view of the file listings, which helps a lot. Video file compatibility seems pretty good
So far, with the BD670, I've successfully played the following file types over a DLNA share: mp4, m4v, mkv, and avi. I wasn't able to successfully play .mov files.
Encoding tested:
Video: x264, XViD
Audio: AAC, AC3, DTS
(Note that for my testing, the above encoding schemes were listed as part of the names of the file I tested -- I didn't spend time independently verifying the encoding schemes)
I'm impressed by the above, given that my old Oppo BPD-83 can't seem to play a whole lot of files through DLNA, though direct USB connection offers far better compatibility. The Sony S580 is also highly limited when it comes to being able to play video files over DLNA.
Video quality for the above file types seems really good -- better than the Sony S580 -- subjectively anyway. Audio seems OK, and by that I mean that I downsized recently to a Bose Cinemate II system to cut down on clutter in my living room -- the system sounds good for what it does IMO, but just not great.
Generally most of my content is 720p. So far, I've not played through 1080p content completely -- there is a pop-up message which states some content may not play correctly. In one case the LG BD670 crashed and restarted on a 1080p file.
However, no luck with getting CIFS login to get to my SMB shares on my MacBook Pro. I keep getting network errors - not sure if this is the problem others are referring to as far as the LG BD players not being to 'see' Mac OS X Lion SMB shares.
LG Dislikes:
1. The LG player's UI seems a little sluggish compared to the Sony S580 UI. The LG UI has fewer items available, but forces you to dig a few levels to get to what you want. The Sony remote also feels 'faster' IMO, but I tend to like the Sony remotes in general.
2. The LG also seems less graceful in recovering from file types it can't play. A few times, I got frustrated waiting and just pulled the AC plug from the wall.
Hope this helps anyone trying to do the same thing.
