I'm looking to purchase a new HDTV for use with my Myth box. Due to space considerations as well as the reviews of some of the better Plasma TVs, I'm leaning towards Plasma. Do many people with myth use plasma? Are there concerns (burn-in) with watching 4:3 shows on an HD plasma display? If so, are there any workarounds (besides exiting out to the main screen every hour)? Thanks, Brian
