Need to check with your experience and exposure with Plasma TV. In the midst of considering between this V20k and the LED 42 of Panasonic before purchasing it.
I know that Plasma has much better PQ than the LED.

Main concern is the Image Retention and Burn-in issue with Plasma. IR is more common from what I read here. Was thinking of using the TV also as a HTPC, does it pose problem for IR? Is LED more suitable for HTPC purpose?

Say occasionally one actually does dose off into deep sleep while the Plasma TV is still running, so IR occurred, can it be resolve?

Since normal DVD players is still used and because the movie will be showed in 16:9 which is clearer but contain two black bar (upper and bottom with subtitles), does it cause a concern of IR? Changing it to full screen with Zoom function does make the quality of the picture degrade somewhat.
This concern goes the same for certain Astro channel with some network logo, I presume.

Not sure whether this Plasma or LED is more suitable in choosing the right TV.

Thank you for your expert opinion in advance.
