Can you try to put your Mede8er video on a fixed mode, so e.g. 1080p 50hz?

And it fhat doesn't help, you might try the V4beta4 firmware.

Hi there,

Thanks for your reply. Do you mean put it in fixed mode when the problem arises to see if it works again? It works fine in auto mode until I transfer a file.

I have tried the V4 firmware and got no sound at all with that and so had to revert back to 3.04. I think, but I can't be sure, that the sound problem started after I tried the V4 f/w.

No, I mean put it always on a fixed setting.
Your problem sounds like some HDMI sync issue and it might be a solution then to set it on a fixed video mode.
