Hi I recently bought this player from Argos.
I thought it was multi-reg because I saw it demo`ed in an independent.
But I think Daewoo have recently changed the spec.
You can use a hack (which is the same as the Scan machine reviewed on this site)
to access a hidden page but the bypass function no longer appears available.
There was also a function to disable Macrovision but this also appears to have been removed.
All the same I think the Daewoo is a very nice machine for the money.
