So, I tried re-encoding the source using Handbrake, and the play back on the TV is still pretty poor. It's better than the original file, but it still looks like frames are dropping, and the audio is out of sync. Here's the media info of the re-encoded file:

As a test I also encoded the file using MPEG-4, which worked a lot better:
