How to re-encode MKV to MP4 for Roku 3?
Officially, Roku 3 supports MKV. Bu many people have been having some issues with certain MKV files playing using the Roku Media Player What happens is that at certain points while playing the MKV file there will be a slight blip and after that blip you will no longer get audio. Another case, when you play MKV file on Roku 3, they constantly stutter and skip as if they are in slow motion.
There are many explanation in the Roku forum. One is to say that as your MKV is AC3, Roku basically only supports it on passthrough. Meaning you have to have a receiver that can handle the AC3 audio. So even if it’s two channel AC3 it can’t play it natively. We hope that they could fix this in a firmware update or something. Another reason is Roku 3 USB Media Player channel only plays MKV files encoded with H.264 video codec. If the MKV is encoded with other video or audio codec like MPEG-2, WAV and etc, we will fail to play MKV on Roku 3 via USB drive, SD card or external HDD. And there is also some saying Roku 3 does support MKV but @30 fps, maybe that’s another reason for the problem.
No matter for what reason, you just got unideal MKV playback on Roku 3 with bad audio performance. There are two solutions to help you. Method 1: try Plex. Plex is a common answer in this sub for these types of questions and is an awesome option, but it can be overkill depending on your needs (and requires a “server” to be running).
