BD rebuilder and Panasonic standalone player

[anthonyplace]

Sorry if this is in the wrong place
I use bd rebuilder to create BD 5 disks I have tried a few different softwares but bd rebuilder is the only one I can get to work (windows 10)
The disks I create work fine on my Sony, Samsung and Denon players are not recognised at all by my Panasonic DP UB 820
Can anyone tell me how to fix this issue is it the folder structure?
Strict AVCHD is ticked

Thanks
