I've got a brand new DVD-player, (TEAC DV-3000), and it worked fine for about the 6 first movies I've watched. (Original DVD-disc's bought in stores.) When I watch my DVD's now, the picture randomly stops for a second, then it will speed up to catch back up with the audio, (this happens every 5th second.) How can I fix this? Also the DVD-player adds some coloured blocks ("big pixels") to the TV-screen, any ideas on this either? Thanx! Greetings from Norway!
