I own a 52 inch HD ready widescreen CRT RPTV. My friend who also owns a RPTV says that I should not watch 4.3 autoformat tv shows or movies on my widescreen TV. Because eventually it ruins the CRT display. Something to do with only projecting a certain area and not projecting the edges enough while watching 4.3 viewing. He says to always zoom it out to full wide or stretch mode. Any truth to this? Is it o.k. to watch 4.3 a long time without effecting the picture and display. I like to watch the original either in 4.3 or wide. On tv, its autoformated to whatever the TV channel is broadcasting. Most channels are still in 4.3 mode. Thoughts? Thanks.
