Slowed Remux Playback

Just wondering if anyone else has run into this problem. It’s not quite the “MKV Full HD Stutter” issue…

I’ve experienced periods of slowed playback speed with remuxes with both the WD TV Live Plus (several FW versions, up to 1.06.16_B) and the WD TV Live Streaming (original and current FW.) Remuxes, of course, are always 1080p HD.

I’m using attached storage (Seagate GO 320GB  & GO 640GB external drives.) The files play perfectly smoothly on a Seagate Freeagent Theatre+ Player and my PC. An example…

There are some users reporting this, no resolution thou, I have not encounter this specific issue, but I can do a file similar to this one and do some test.

Thank you. Much appreciated.
