I have the Panasonic Tau CT-34WX50. I have my Xbox set to widescreen mode, and it is connected to my TV via the component inputs. So far I have played all games that do not support widescreen in stretch mode and they look great, so I never bothered changing the TV to normal aspect ratio (4:3). I have games like HALO, PGR, SSX, & Munch's Oddyssey. So yesterday I boot up NFL Fever and it doesnt look too great stretched out and I tried to change the TV back to 4:3. The aspect ratio would only switch between FULL and ZOOM modes. I consulted the hardware manual for the television and learned that when a 1080i or 480p signal is detected thru the component inputs, I could only switch between the ZOOM and FULL modes. Hmmm. So... I start thinking that maybe its not worth it to use component inputs (High Definition AV Pack) and switch over to S-Video (Advanced AV Pack). Will I suffer much video quality loss? Is it worth it?
