Not very good at playing M2TS video files

I Installed proplayer on my ipad2, followed the instructions to copy a sony video file with the extension .M2TS which it is supposed to support, I start playing the file, the audio is good, the resolution is OK, but the video does not keep track with the sound, no movement within the video. I had high hopes, but this app still needs refinement, dont buy this version for now
