I have recently purchased a Philips 612 DVD player, and have noticed a slight flickering on the TV screen during play back of discs. Having never owned a player before I am unsure as to whether this is normal (like you get when playing back videos) or whether they may be a problem with the machine. Can anybody help? I have hacked the player using a code off the internet - could this be the reason? The player is connected to the TV using scart leads. Thanks for any info.
