OK, so I bought the 320 this weekend, and here is what I am running into. It is driving me crazy!
Playing MKV files from USB works flawlessly.
Playing those same MKV files from a network share (Tried Windows XP, 7 and Ubuntu 12.04) is VERY slow. 720p content chokes up every few minutes, and 1080p content is just horribly slow. I look on the fileserver end, and the network is only hitting about 1.5-2.0MB/s. It is a 100 meg connection from client to server, and just one switch in between. I even tried my laptop directly connected with a crossover cable, and just a couple link-local addresses to remove anything else from the network, same thing. My guess is their CIFS implementation cannot handle the I/O required to play the files.
So I tried DLNA with PS3MediaServer, uShare, MediaTomb, and even Windows Media Player. The Bluray player wont even touch the MKVs with either of them serving it up. It is just an immediate "Cannot Play" without even an attempt. FLAC will play with everything, with no transcoding, and when Transcoding MKVs with PS3MediaServer, it produces a green garbled mess of randomness.
What in the world is going on here? I contacted Panasonic Support 3 times, and each time they say that if it can play via USB, then it should play via DLNA just fine, and they tested/designed it with WMP in mind for serving up the files. They even tested it on the phone with me and it worked fine for them on their end.
I tried putting just the video in an MP4 container, and it played that via DLNA flawlessly with the network peaking up to 3-4MB/s as needed.
Is anyone else having these same issues? I am ready to throw this thing back in the box and send it back to Amazon.
