DVD resolution 480i vs 480p questions

Archived from groups: alt.tv.tech.hdtv (More info?)

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.

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

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?
