Well...I've seen some odd things in my time, but this one has got me stumped for a suitable answer... I have a commercial DVD which will only play on a CRT TV set. Whenever I try to run it on my PW7, i get an effect similar to losing the horizontal hold on a telly (remember them...) and the picture rolls and flickers, colour goes in and out...really strange... So...I tried another DVD player, and its the same on that too...Took it to work, on their Sony CRT, and volia...sorted... Any ideas???
