After lots of confusion and head scratching.........All done
..... following very carefully Raydon's instructions from post 28.........All 3 Humax boxes...." cross mounted " / connected together ....and all SD recordings can be viewed from ""USB1" / sda 1 (2)....on the other 2 box's.....
.......
The Panasonic Tvs still won't play back from the humax boxes....But strangely my Panasonic DBP-BDT260 Smart Bluray player will play back SD recordings from the 3 Humax Boxes perfectly...? ................
Next step is how to get HD recordings to play.............How do i install a "Nowsters patch"...? ..............
Again .......A big thanks to everyone ........
