It seems that a codec required to read these video types is missing. Even though the file is an MP4 or TS, there are different codecs which can be used to encode videos, and the codec used on this particular file is not fully supported in MATLAB. In addition, it is likely that without the codec you are able to play the video using the Windows Media Player.
This can be resolved by downloading and installing an appropriate codec pack.
