Had a similar issue to others that the above change didn't "stick" after powering off and on. I've since changed the Language_Arabic option = EU and Region = KOR (only options I see are USA/KOR). This seems to have caused the PVR=ON to remain on all the time so I think I'm on the right track..
Now when I plug in a USB HDD or a USB Stick, I still cannot record anything.
-Yes, I can select the USB stick and the USB HDD and browse files but no option to format appears.
-I've tried to open the guide and schedule a recording (in order to bring up the format option others seem to have found) but no dice.. I just continue to get a "No USB Connected Please Check Connection" message when I attempt to record...
In case it helps:
In another post someone had claimed that the PVR function will not work on J versions of the tv - only JU versions will work (ie. JU5500). I don't now if that's true or not but I do see that those who have the "J" version in the european TV (ie UE48J5500) are able to get the PVR working.
I do note that the extended menu is different in the euorpoean vs north american sets so maybe it's firmware related. Can a US set be changed to the European firmware for the same tv?
"No USB Connected Please Check Connection" or "Not Available"?
Pvr only works on the 1A rated usb port
