Phoenix Nights/Multiregion query

I have just purchased a boxed set of Phoenix Nights 1 and 2.  DVD 1 plays
fine but DVD 2 will not play.  It goes through the DVD advert bit at the
start etc. but when it comes to start playing the actual series, the DVD
player displays 'STOP'.

Both discs seem to be the same format they are region 2 and my DVD should
play any region 1 to 6.

I have checked the rating level and it is set to highest.

I have exchanged the DVD's at Tesco but still the same problem with disc 2.

I have then tried the disc in another player and it played fine.

Should the DVD Player be replaced or is there a fix?
The Player is a Mico 3000 which came from Sainsbury last year.  In all other
respects it is fine.

Any help would be appreciated.
