Hi I'm using a Pioneer DV-350 DVD player and I have a problem when playing Region1 dvd's. The player is multi region and used to work fine but recently I am getting strange horizontal lines accross the screen but only with R1 disks. The dvd player is fine on another tv. I am connecting using a Thor scart lead. The AV2 scart on the TV plays without the strange lines but it flicks between colour and black & white every second or so. The problem seems to be a setting somewhere but after fiddling with both my tv and dvd player it's still the same. Any ideas?
