Thanks. I just saw that. I'll play with it tomorrow as it's about time to hit the sack.
Meanwhile, after some testing with several different settings and even my router's broadcast channel to try and figure out why DTS MKV video stutters, I'm still at a bit of a loss. Lowering the bitrate or quality settings for a video to encode in Handbrake does not stop the stuttering (just makes the picture worse). The weird thing is that if I encode multiple audio tracks (the rest non-DTS) and switch to a different audio track, the stuttering problem disappears and the video plays back normally. This occurs with both XBMC and Boxee (I am streaming both over SMB shares).
However, in Boxee, it shows a dual-color progress indicator and it's clear that it's buffering a certain amount ahead of where it's playing and will only load as it goes (it does not attempt to keep loading/storing the video on the hard drive like something along the lines of an Apple movie rental would do). But the difference I see when using a DTS audio track versus a non-DTS track is that with the non-DTS tracks it seems to more or less keep pace a certain distance ahead of the playback point on the graph, but with DTS selected, it will load a certain distance ahead (grey bar) and then the playback point (yellow bar) will almost, but not quite catch up with it and then all the sudden it loads way ahead on the grey bar and just as it stops loading any further on the grey bar, it stutters and then playback continues and the yellow bar almost catches up and then it loads and just as it stops loading ahead it stutters again at the same pattern over and over. Again, selecting a non-DTS track seems to keep a nice even pace on the buffering.
I have no idea why there's a different pattern there, but the fact the stutters seem to occur just after loading a big buffer seems like whatever is happening isn't some random thing or the WiFi signal going patchy or whatever. I'm curious if others on here are playing back DTS MKV files on their AppleTV units over WiFi and if so whether they are having any stutter/pause/buffer issues with them. They seem fairly consistent here regardless of bit-rate settings, length of feature (even the DTS Trailer which is very short will stutter, usually at the same points each time) or even whether I use XBMC or Boxee. I don't know if there's a hidden setting somewhere that might help. I plan to read the online manual tomorrow and see if there's anything that might help with DTS audio.
