I've just received a Tosh 330 as a present for my dad but when I plugged into a fairly ancient JVC AV-28WT2EK widecreen TV the 4:3 image flicks back and forth with Full Screen. This applies to both 4:3 DVDs and the players setup screen. I've tried seeting both the Tosh and TV to fixed 4:3 format and it still does it. My other DVD player works fine with this TV. Any ideas or is there likely to be a fault?
