Anyway getting back on thread - they have stuck 5 episodes on some of these discs, whereas Region 2 versions only have 4 episodes per disc - that might affect the quality
I might borrow a mate's R2 and see if that's any better. I should imagine it'll be fine. All the rest of my R2 are perfect. Just R1 and R4's I notice these lines.
Someone said it might be a Macrovision problem on the player?
