That should rule out overheating but what I meant about network issues is that some service or server in your network might send packets throwing off the WDTV. For most people, fixing master browser issues allows them to connect to network shares without losing them any more so I guess, it might be something similar in your case. The question is, what could it be? Jumbo frames, UPNP? You don’t experience this playback breaking off on files played from USB, right?
As I wrote here there’s not enough info yet on how to reproduce this bug.
