Hello, I'm a newbie so apologize if this is an idiotic question! Just bot myself a panny 6. Fantastic! It's my first plasma and my first 16:9 TV (the old TV is 4:3). When I play my DVDs, I notice that I had to switch it the panny to 4:3 aspect since the DVDs seem to be "letter box" format to fit 4:3 TVs (all region 1 DVDs BTW). Of course when I view the DVDs with 4:3 on my panny, about 50% of the screen is blank! Is there any way of curing this or it's a case of buying new DVD discs. I use a ARCAM 88 BTW. Many thanks!
