I too noticed stuttering using a Sony BDS-580. Some files play perfectly using wired connection, and some stutter.
Files that stutter that will fit on a 16Gb USB flash drive (or have been cut down to test) play perfectly when plugged into the player, so the file itself is not the problem - MKV, TS and M2TS tried. They also play perfectly using my PC and Media Player Classic.
I had noticed that movies encoded with the latest TRUE-HD and DTS 7.1 were worse. The Sony reports file playback rates at just under 40Mb/sec during peak times, which is well within my network capability. Tried transcoding to lower audio using TsMuxer, but that didn't work either.
I also tried other free DLNA software (none I found were any good) and Mezzmo, which is priced! Mezzmo couldn't handle these files either, even with their own transcoding methods. Their support advised there was a known problem with Sony and DLNA at higher rates and have developed transcoding to supposedly deal with this by limiting the stream rate to 20Mb, but this didn't work for me either.
As an aside, Mezzmo does things a lot better than Serviio! It is easier to use and a lot faster in loading, updating files etc. This is not a plug for a free version - I didn't buy it as I couldn't get it to work with the stuttering files either! - but for some users I can see it would be a lot better than having to nursemaid Serviio all the time.
Does anyone know of a file I can try that has a known constant bit stream which could be adjusted? I was thinking of trying some increasing bit rates until stuttering occurs, in an attempt to know if it is worth limiting the video or audio rate, or both.
I also wonder if the problem is inherent in the files themselves, perhaps dodgy encoding techniques, simillar to some MP3 problems.
Does anyone know of a good way of testing this?
