Hauppauge HDPVR Playback

I use the Hauppauge HDPVR to backup programs from my DISH DVR.  These files are 720p M2TS before I convert them to MP4. These MP4 files play back fine if I import them into iTunes, but XBMC cannot play the M2TS files (or the MP4 files) at the proper speed.  Will the built-in media player of aTV Flash (black) be able to play these files properly?
