Deinterlace and Convert Sony AVCHD Camcorder Videos to M4V for QuickTime Pro

I have a question on block artifacts that I get when I try to deinterlace a movie made with a Sony AVCHD camcorder. I first repackaged the original .MTS file from the camcorder into an .M4V container using ffmpeg. This allows me to play the movie using QuickTime 7. (In order to hear the audio, an AAC codec is also required by the way.) If I try to deinterlace the movie, I get block artifacts. I tried several settings and various output formats, but to no avail so far. Maybe I am missing something obvious?

Some free software like ffmpeg, tsmuxer, etc can be used as AVCHD Converter or Remux tool, but for they can not guarantee whether the output audio is in sync with the image, and the most importantly, 1080i interlaced AVCHD files can not be showed more clearly after repackaged. Now I will introduced an useful and powerful Mac Sony AVCHD Converter and Deinterlacing Tool, which can help you deinterlace Sony AVCHD camcorder videos perfectly and convert to H.264 AAC M4V for playing on QuickTime Pro.
