Samsung and ""Preparing to play"

[pbelisle]

I've recently begun having problems playing back HD home movies with Mezzmo on my Samsung UN46C65000 LED: the movies pause briefly while the "Preparing to play" displays. These annoying pauses occur randomly and repeatedly throughout the movies. Curiously, Samsung's own DNLA (PCShare) plays the movies flawlessly as, once, did Mezzmo (edit: that was true earlier but not now: playing the movie on PCShare resulted in a half-dozen playback delays).

These movies are (edit: MP4s) approximately 7000 KBPS, 1920x1080. Mezzmo plays run-of-the-mill (edit: MP4) files (eg., 1500 KBPS 1280x720) without difficulty.

Any thoughts appreciated.
