When I was streaming from my PC to the Pana, I had the same "cannot play video" issue, but I installed PS3MS (ps3 media server) on the PC and it seemed to work OK when I used the pana to navigate there instead of just file-playing (some files still wouldnt play, and some TV shows had voice sync issues, but 90% were fine).
I've since moved from storing media on a PC to a NAS and using multiple WDTV's around the house. This setup works well.
I had the same "video cannot play" due to access credentials on my BMP120. There is option somewhere (network?) to add device to read from (up to 5 devices or something). Soon as I added IP of my NAS it was not a problem anymore, but still had problems with subtitles in mkvs (just couldn't read it from external files, no matter what).
DLNA is very annoying in long term usage (too many profiles and every manufacturer has its own implementation of "standards"), but this is just my opinion, also it require CPU power to transcode (sometimes a lot, especially if you running it on many devices), so if you after "green" media player this is not very green (it will re encode the same movie every time you are watching it). Best setup I've found so far is (if you want to incorporate NAS) just run SMB (windows share) and read it from there (many devices will allow to do it) but you have to bear in mind things like passwords and accounts, or like me just build Media player based on x86 and slap few 1tb/2tb 2.5 hdds (they are getting cheap) running great OpenELEC system (it boots from cold stone to full operational in 20 secs or 1.5 sec if you using sleep mode)
Some people say that AMD GFX cards have "better" picture, but... if you are compressing from BD (25GB) to 2.5-5GB mkv file, then I don't think you will find many differences anyway.
It's all to do with WHAT you want from device and NOT what you will get from them. I want HD sound via HDMI and fully operational system where I can stream what I want where I want, so this OpenELEC was my answer for this call. To watch mkv/avi/mpg this setup was PERFECT, but it can do so much more than just that.
The only hiccup is Netflix player, OE is free so people doing it in spare time (it is better than many FULL TIME written programs anyway) and things like Netflix or Amazon prime are proprietary software and they don't want to share it for free, so OE needs to do reverse engineering if they can if not... tough luck. BUT, they are things around it so you can always find satisfying solution. My way out was that I have a Virgin Media and it has Netflix player on it, so... it was all I ever need it. All my sharing, playing, streaming from phones, watching pics is done in OE, Netflix runs on Virgin Media, simple. ...and it doesn't affect my broadband bandwidth as I "don't" use it via my router but via VM player directly. It's like watching Virgin on demand, no slowdowns/penalties for heavy using my broadband hehehe...
As for great audio/video from Panasonic: audio is just DTS HD/TrueHD bitstream to my Audio Video Receiver and from there is divides on 7.1 speaker set, video is still great as NVidia/AMD know their stuff. You will not see difference with Pana if you set up the same parameters. In case you want to watch 4k movie... This is a totally different story, as for 2014/15 only way to get it cheap is x86 system... and there are no 4k BD player as far as I know... but I can flip a switch on OpenELEC and if my GFX card and TV allow me I will get 4K without much fuss... Beat that ;-)
...last thing... Synology, synology... It cost a 4x amount of money I wanted to spend and it cannot do half as much as I can do on my NAS4Free system. All I ever need from my NAS is resilience and data safety... I will say: ZFS RaidZ2 (6x HDD) and 32GB ECC memory... How much you will have to pay to get that from Synology? OK, for most of people it will be great, but for those who lost valued pictures just sitting on hard drive after few years... and I didn't know until I had a look there... thanks, but no thanks! ;-)
