The Roku 3's excellent interface and speedy processor makes it feel quicker and more responsive than any other streaming box. For most of us, it was the combination of on-demand media and easy access to our own extensive media library that made Roku's case, not to mention an attractive price tag. Officially, the Roku 3 supports H.264 MKV and MP4/M4V video (the only media recognized over USB and Plex' Direct Play). However, most of the time you will find it a painful experience to enjoy MKV videos with Roku 3. Get frustrated? In fact, it is easy, fast and worth the effort. This tutorial mainly explains you how to play all your MKV files on Roku 3 directly.

As far as I know, MKV is the norm for high definition video content. Usually, these files have a 5.1 surround sound audio track. There are two issues with these 5.1 audio MKV files. The main issue lies with Dolby Digital and DTS audio. These files only work over USB and the audio is only supported via pass through. This means Roku won't help you out if your system doesn't support 5.1 DTS audio.

To get those MKV files and Roku 3 to play nicely, the easy workaround is to transcode them to a compatible format. EaseFab Video Converter is a great application to convert your video files. It has a codec pack that enables conversion between different video and audio file formats, it can convert MKV, VOB, MOV, FLV, MPG, AVI to Roku 3 supported file format such as mp4 with the best quality.

How to encode/re-encode MKV to Roku 3 compatible format

Step 1. Load MKV files to the converter

Download and install video converter for Roku on your computer. Run it and directly drag and drop the MKV files that you want into the main window of this converter. You can also add MKV files by clicking the "Add Video" button on the left bottom.


Step 2. Select Roku supported format

Click "Profile" and select MP4 from Common Video as the output format. The reason mp4 is the target format is that by packing the videos in mp4, the file size will be reasonable small and the video quality remains.


Tip: There are also some optional tinkering you can take to make the videos look better on a HDTV screen, such as changing the aspect ratio or specifying the video resolution. Just click the Settings (beside Profile) icon to do it.

3. Start converting MKV for Roku 3

After everything is ready, hit the big Convert button to begin the MKV to Roku 3 MP4 conversion. As long as get the output MP4 files, you can either stream them or transfer the converted videos to Roku's SD card or to a USB stick that can be attached to Roku streaming player. Now you can enjoy your MKV movies with Roku 3, Roku 2 with ease.

Additional Tips:

If your movie (like MKV, VOB, AVI, MOV, MPG, etc.) isn't already in one of the Roku supported formats or it's still on a DVD and Blu-ray, you'll need to encode/re-encode it first. To get all the work done, you can get the all-in-one app entitled Video Converter Ultimate to make it.
