Got an Allegro ABV441 DVD/VHS Player, the label says made by Zenith.
Found Zenith on the Region Hacks area of this site and was sent to an Aiwa player hack which worked fine. (Pause 314159.. 0 then Pause..power off...power on)
(The Firmware reveal hack after resetting the region to ) still shows Region 1 so I am assuming this is just burnt in).
Hope this helps someone.
