Hi Longedge -
My Sony UHD TV - KD55X8000C - doesn't give me such grief. I mainly use a Seagate 1.5TB portable drive.
No MP4 I've ever produced in PDR has ever failed to (a) be recognised or (b) play correctly via the TV's inbuilt media player. Never have to re-format - just plug iit in, choose media, scroll to the file & play. I also plug in the laptop, via HDMI, when I want to get the best out of it.
There are formats, like M2TS, that the Sony doesn't like... but never a problem with MP4.
Cokeaddict57 - have you used MP4s produced in PDR on your TV previously? other MP4s? As Carl suggested, there may be something in the user manual that will give you a clue. That said, mine doesn't!
Cheers - Tony
