I am experiencing serious frame drops on several movies when played on any of my Roku3 devices. Movies are played directly (without transcoding) but the image has little movement: it seems a sequence of stills with a lot of frames dropped in between them. Same movies play fine on Windows 8 app (direct play) and on Chrome browser (transcoded). This does not occur with all movies, so I did lots of tests to better determine the scenario (e.g.: codecs) that causes this phenomenon. The common factors to every movie with this problem are: Container: MKV Audio: AC3 AVIs with AC3 audio streams are not problem as they all get transcoded. I disabled AC3 (DD) passthrough on the Roku configuration. This setup made MKVs with AC3 audio streams to be transcoded. As they are transcoded they play fine with no jitter/frame drops. This is, though, no solution: disabling AC3 also disables DTS and thus all movies are transcoded resulting on only on 2 audio channels. I suspect this problem relates to Roku's new firmware as these movies used to play fine on same Rokus. So if anybody could just test MKVs/AC3 on a Roku and share the result it would be very good. My setup is as it follows: MB Server version: 3.0.5518.7 Roku app version: 1.87 Roku firmware version: 6.1 build 5604
