Hey, I had the same issue for a long time. I could stream the hightest quality 1080p with HD-MA but at some point I just couldn't do it anymore. My playback would just stop (logs would indicate something like "streaming stopped") and I had to pause for a minute and unpause and it would stream for 5 minutes until the problem reappears.
I'm using a Hackintosh with an Intel 3570k running on Mavericks 10.9.2, 16GB and a gigabyte connection. I couldn't really find anything helpful on this forum so here's what worked for me.
I did try a lot of things but it would never work. I finally decided to setup everything so there would be no transcoding and no bandwith problem.
So what I did is
- install the latest version of Java 7
- in the General configuration tab I selected my ethernet adapter on "Force Networking on interface", entered 0 for "Maximum Bandwidth"
- in transcoding settings tab, I first went to "Common Transcode Settings / Video Settings" and put 200 as Maximum transcode buffer, disable subtitles, chose Automatic Wired for Transcoding Quality (MPEG-2), chose Automatic for Transcoding Quality, and then entered *.ts , ts , *.m2ts , m2ts under Skip Transcoding for the following (will explain this in a second). In "Common Transcode Settings / Audio Settings" i chose 6 Channels for maximum number of channels, checked "use LPCM" and "Keep DTS Tracks" and unchecked all the others. Haven't touched AC-3 reencoding and Language priority.
- In Video Files Engines I only chose to use tsMuxer. I check "Force FPS parsed from FFmpeg"
Now, I also found that muxing my MKVs would really work well with that configuration (hence the skip transcoding for *.ts , ts , *.m2ts). So I downloaded tsMuxer GUI and I convert to TS all my MKV. No options to configure for me, I just drop the MKV and press Start Muxing.
It seems tedious but since I've set it up that way I had no issue what so ever. No lag, no pause, no out of sync. Probably half of the things I did there weren't necessary but I got tired of testing again and again and failing.
Here are screenshots

Good Luck !

EDIT : I only mux high quality 1080p DTS files. I have no issues with 720p. By muxing the files and tell UMS to not transcode, the computer will just stream the file and not decode/transcode it.
