Digigriffin,
I came to the v10 from a cheap 26" samsung lcd (2 years old), which was pretty bad with freeview (better with sky), and not really very good with dvd. From the testing I did before I bought the set, I was very impressed with the dvd playback, and blu ray.
I haven't seen very much dvd content because I don't have a blu ray (or dvd) player yet, but it was definately a considerable step up from my previous tv's performance - as you'd expect from a tv costing five times the price. Same again with tv, though I concede it doesn't look amazing, it's better than what I'm used to.
Simoncar,
Thanks for trying that out. I guess I'll have to see what the store I bought it from tell me tomorrow. They contacted panasonic who advised I reset the tv to shipping conditions. I can't see that having too much of an impact, but I'll have to wait and see.
At least the demo tv I was showed has it, so they are aware of the problem, even though it is worse on mine.
P.s. I think if we were into saving the planet, we wouldn't have bought large(ish) plasma tvs, lol.
