I got the Ailiens dvd box set and Drunkenmaster (all R2). The Ailiens dvd featurettes do not have any sound, the film is fine and all the other dvds work ok. On the Drunkenmaster dvd after about halfway through, track 12-14, the picture intermitantly starts to get block eventually getting worse and making it unwatchable. Both discs are spotless, brand new out of virgin and i've never had anyother problems with the player (wharfdale dvd750) or other discs before, rented/new/seconhand. I always make sure any discs I use are clean and if not I carefully clean them (bloody blockbuster!) The player is connected via RGB scart to a widescreen grundig tv - but i'm sure thats not a problem. Anyone got any suggestion why this is and how to remedy these problems. Any help would be great because these are my two favourite films.
