I’ve talked about how to get AVI videos onto Roku 3 with smooth playback before. Well, in fact I have a lot of video files, mostly .vob from my DVD collection. I cannot find a clear answer on if and how well the Roku 3 will play these VOB files using the USB port with a flash drive. So how can I play VOB files on Roku 3 easily? I have scoured the internet, tried everything I could find.
Solution 1: Rename VOB to MPG
Some guys mentioned Roku should be able to play VOB files. The problem is – the Roku software isn’t looking for .VOB extensions, so it doesn’t know to play them. All we have to do is rename their extension to .MPG (which of course will screw up all your other *real* DVD player software) and the Roku 3 will play them.
Result: I’ve tried the way, but no luck.
Solution 2: Convert VOB to Roku3 more friendly format
There’s an other workaround that can make VOB movies playable on Roku 3- Encode VOB to Roku 3 officially supported MP4 videos.
Result: I’ve achieved the success playing VOB on Roku 3
The complete guide about how to convert VOB to Roku 3 supported file format
The software has a codec pack that enables conversion between different video and audio file formats, it can convert VOB , AVI, MOV, MKV, FLV, MPG, etc to Roku 3 supported file format such as mp4 with the best quality.
1. Start video converter, drag and drop the VOB files to the software window to import.
2. Click Format > Common Video and set output video format as mp4. 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: Click Settings icon, you can adjust the video, audio parameters, such as changing the aspect ratio or specifying the video resolution.
3. Hit the Convert button to start converting VOB to Roku 3 playable MP4 video.
