Hi champs,
I need your help in choosing a new Plasma TV for our living room (we will move our old one a Panasonic TH-37PE55E up to the guest room).
Even so HD etc. is somehow standard these days, we still use an SD DVB-S STB (Topfield 5000er) and continue to consume 90% SD TV signal (Free TV over here in Europe) with standard resolution (PAL SD i.e. 720/704 x 576) and a mixture of aspect ratio of 4:3 and 16:9.

So, we kind of liked the picture quality of the old Plasam, even the native resolution of the TH-37PE55E is only 842x480, but IMHO Panasonic did some very good scaling algorithm to fit SD 4:3 very nicely on the 16:9 screen, and some good ways of automatically switching between 4:3 and 16:9 without too much trouble.

Now we are thinking about the following 2 Plasmas from Panasonic:
TX-P42X50E with a native resolution of 1366x768 (kind of 720p)
TX-P42UT50E with a native resolution of 1920x1080 (kind of 1080i)
As you can see, we are looking more in the budget level, but reading through the reviews, it looks like both Plasmas are not too bad at all.

However now we are unsure which TV would provide a better quality, based on our consumption behavior (primarily TV SD signals!).
Which one does the scaling/ fitting better? IMHO the TX-P42UT50E might be able to simply 2x the pixel of a 4:3 SD signal and fit it fully on screen (black bars on both sides), but not sure if that is the right way, will be done like that.

Any feedback/ advice/ recommendations?
Thanks a lot in advance!

HDTV broadcast at 1080i will usually look better than broadcasts at 720p, but chances are that the 720p set will also do 1080i (at least USA Panasonic 720p sets also do 1080i).

The UT50 is actually a 1080p native set, but accepts all standard formats including 480i, 480p, 720p and 1080i and will upscale and/or de-interlace as needed.
With a smaller size set like a 42" at typical viewing distances, you probably can't see the difference between the 768p or 1080p anyway.
What will be your viewing distance? SD video will look better viewing farther away from the set.
