Another possible issue. Some people have reported a problem with visible "seams" or "lines" in the picture with they try to feed HDTV into the Panny ED via the VGA port. I saw these using a DTC-100 when I first got the plasma, but was able to make them essentially dissappear by diddling the vertical size control. Some haven't been as lucky, and some have never seen them in the first place. so it's a variable problem. (I don't believe I've ever heard anyone report the "seams" problem with the HD set.)
The problem is that Panny says the VGA input on the ED plasma is intended for and optimized for computer input. Running HDTV into it is not something they officially support. So, if you run into this problem with your set, they won't help. You could do a search of this forum on those topics and read all about it.
Panny engineered these sets to run PC in via the VGA port and HD via those BNCs, either as component or RGB. To do that with the DTC 100, you have to get either a VGA-to-RGB breakout cable or a VGA-to-Component transcoder. Everyone who's reported on doing it this way says the PQ on both sources is great.
