I've had an RDXS34 for a few months now. All good stuff but I find it doesn't play about 50% of DVD's I try in it. It seems to be highly fussy, even with brand new films or programmes. They all play fine in other DVD players I have but just not on the RDXS34. Does anyone else have this problem with their machine? Does anyone know of it - as a known problem on this model? Can anything be done?.. Many Thanks..
