The current Roku profile transcodes into .TS, and the only containers that are not transcoded are MKV, TS and MP4. Also, if the video inside those containers are MPEG2, they are still transcoded.
So, if your video is in the proper container and uses H.264 video, you should be able to FF/rewind. Almost any other container or video codec will force transcoding to TS, and you lose the function. You could change the profile to use HLS instead of TS for transcoding, and I believe that will restore your ability. I'm currently working on a profile specific to the Roku 4, since it supports H.265 without transcoding.
So, exactly what sort of video are you playing? Container, audio and video codec? It may be transcoding even when you think it's not.
Thanks @atc98092. A file example of container, audio and video codec are listed below. When I was using the Buffalo Linkstation with Roku Media Player, trick play worked just fine. The Linkstation didn't transcode either. Running this same file through PlayOn server using Roku Media Player, for example, trick play is available.
