Act 1 video player plays FLV on EE, however only distorted. It seems the EE is slow for it.

FLY file: video codec H264 - MPEG-4 AVC (part 10) (avc1), 854x480, 29 fps, auido codec MPEG ACC (mp4a), stereo, 44100 Hz


What could be the reason that the EE plays is only distorted?
Is there any better video player for FLV on EE?
