Solving playback issues

[WOX]

Hi Today:

    Some  mp4 files don't seem to be recognized by the ROKU Player..Some files will only play the "AUDIO"  Some work perfectly. some don't play at all..  Is that issue able to be "FIXED" ??

  Thank You, for a quick reply yo my message..

@WOX, that's not an easy question to answer.  The file extension doesn't necessarily mean anything - it's what's in the file that matters.  There's no easy way to get that information other than using another media player on a computer that can give the video's properties or a utility like MediaInfo.  Roku devices support a limited number of codecs.  You can see the list here:
