DVD resolution 480i vs 480p questions

The upconversion electronics in my Sony gives a better picture than the
upconversion electronics built into my progressive scan DVD. So, I leave the
DVD on 480i and let the Sony do the job.

I think the point is that while there may be little difference between 480i
and 480p in terms of picture quality, there can a be noticable difference in
upconversion systems.

Just got my fancy 43" 1024 x768 Pioneer plasma TV from Costco. I hooked the
TV up to a cheapo DVD player (assume it is 480i). The TV does image
processing including the 3-2 pulldown, and the TV also converts all inputs
(480i, 480p 720p and 180i) to 768p. Is it worth for me to get a progressive
scan DVD at 480p, or does the TV already do the upconverting to 480p from my
old DVD 480i signal?
Is the difference between 480i and 480p very much? Is it worth gettting a
progressive scan DVD or should I just wait?
Also there is talk of DVDs with upconversion to 1080i? It is my
understanding (correct me if I am wrong) that DVDs are native 480p. Is the
upconversion worthless marketing propaganda? Also does my TV already do
upconverting?
Thanks in advance

The resolution is the same. Under ideal conditions the apparent resolution
of the progressive conversion will look better. But remember, most digital
sets, and almost all fixed pixel sets, do not display either a 480i or 480p
native resolution. Thus, under ideal conditions, sending the set a digital
480i feed and leaving up to the set to do the conversion once is ususally
best.

Switching from a progressive scan Sony to the Toshiba SD-5980 upconverting
player made a huge difference on my Toshiba TV at 1080i.

I have my DVD connected to my set with component input cables. When I
switch to Progessive scan in the DVD I get a brighter picture with more
resolution (on most media,some don't show any difference). I think that
outputting 480I from the DVD has less information that the 480P output
regardless of who is doing the conversion. Think about it. 480I throws
much of the information away that is in the data stream from the DVD media,
once it's thrown away by the DVD player it can't be replaced by your TV.
480P has 100% of the information in the data stream. The case can be made
for the 1080I upconverting DVD players that THEY may not do as good as your
TV in upconverting from 480P to 1080I.

Thanks to everyone who answered my questions.
So far,

David says his TV does a better job of upconverting the DVD player's 480i.

Jeff says his 480p DVD player sometimes does a better job of upconverting
the 480i to the TV.

Galley said, "Switching from a progressive scan Sony to the Toshiba SD-5980
upconverting
player made a huge difference on my Toshiba TV at 1080i."

Galley,
Is the DVD player upconverting the 480i to 1080i? How big of a difference is
a huge difference - like a percentage 20% better or what?

Thanks in advance,

I think you'll find that this all depends on the exact equipment. My
set up with a JVC dvd and an Hitachi TV shows no difference either
way. Does my TV do a better job at converting or does my DVD player
do a worse job. Or is it vice versa. Are they both excellant or Both
bad?

I would buy the TV I liked and a progressive DVD player. They cost
about the same as a non-progressive now. In any case the price
difference will be miniscule compared to the price of the tv. That
way you will have a choice and can use what looks best to you.

I am trying to decide wether it is worth buying a progressive DVD versus
just staying with my old 480i DVD player and upscaling with my TV. So what
say ye?
