The streaming superstar. With up to 1080p HD video and extended-range, dual-band wireless performance, the Roku 3 takes streaming to the next level. You can freely enjoy your own media on Roku 3.
I get a lot of conflicting reports on what the Roku 3 is capable of doing. I found a thread in hear that also talked about multiple streams causing the problem. I’ve checked many files with MediaInfo and they all show that there is only video stream and one audio stream. So after digging deeper into technical specs of the Roku 3, I found different conflicting answers. Video Support: MP4 (H.264), MOV (H.264), MKV (H.264), ASF/WMV (WMV9/VC1) and Audio Support: MP3, AAC, Dolby Digital (MP4, MOV, and MKV pass through only), DTS (MKV pass through only).
Needless to say, AVI is not included here. I chose AVI because of good compression and it is still supported in most places even though it’s very old. I also like the best audio to run through my sound system when I can. So, how to prepare your AVI videos for playback on Roku 3? Luckily, there’s a workaround that can make your movies playable on Roku 3- Encode AVI to Roku 3 officially supported MP4 videos.
The tutorial about how to convert AVI to Roku 3 supported file format
