Resolution Note:
Rewinding video decoding is not instantaneous and requires the decoding to rewind to the keyframe that's before the seek point and then decoding all frames in background until the target frame is produced. Depending on how many frames this requires to be decoded, and how fast a given device is, this can take a long time and is not under Unity's control.
