This one I have to admit i am still not very certain. I have a PV80H which is only HD 720P panel not Full HD 1080P but it can receive 1080P input into the set. In fact if the input is 1080P the picture is better. So i beleive the Panny down scales the 1080P to 720P. Correct me if i am wrong. 

Did not plan out for a Full HD as i am not planning to go with Blu-Ray yet...only when prices are down to earth including the media.

The PV80 upscales everything to 1080p before rescaling to fit the screen (768p + 2.5% overscan). So the best feed to give it IS 1080p to avoid the set having to rescale twice.

If you feed it 720p, it will still be upscaled to 1080p before downscaling to 768. That's just the way Panasonic has designed this TV.

I got that off some technical discussions on the PX80/PV80 on AVS and AVForums.

My own testing, 1080p is more detailed than 720p. In fact a 720p feed from the Panny S54 is softer than just feeding it 480i (TV does all the scaling). But 1080p is better than 480i.

There should be a display/info button where you can see the resolution.

1080p feeds will be downscaled to 720p or interlaced as 1080i for non full HD displays.

If the DVDP already upscale to 1080p, then the TV rescale to fit the screen, that means rescaling still happens twice. First at the DVDP then the TV.

Why bother to have an upscaling DVDP in the first place?

I think you can still watch movie in 1080p if your tv is only in 720p resolution.

I have once saw the panny pv-8 displayed superb picture quality when feeded with blu ray disc in one of the panny promotion fair recently. Its PQ is much better compared to normal dvd play. Again, if viewing distance is within 6 feet I guess. If too far apart, eveything you see is about the same. Be it a FULL hd, HALF hd, SEMI hd or whatever D.....all will look just a square picture projected from a square frame.    However, this is when you really get into the movie not just everytime do the "audition" instead of watching movie.

So, conclusion is if you have longer viewing distance or wanna to benefit from a good story movie, dont bother investing your hardcore money into Full hd tv. Better invest into sound system coz no matter how far you sit, you can still enjoy DD5.1, DTS, DTS-HD, DSP etc etc......provided you have a good receiver. The digital surround can still shooting around behind you with crystal clear effect. 

Err, because the DVDP Upscaller is tad better 

BD's are not an option for me...too $$$

Yup.. I absolutely agree... put more money into the sound system..

Yup $$$ seems the only limiting factor for BD... and also we can find some ehem DVD claimed as transferred from BD at much cheaper price. I do find it to be superior from DVD9 but I don't know whether it is BD-transfer. I don't have BD player nor BD to confirm.

Our *ahem* BDs are just dual-layer rips from actual BDs. I have a few copies of the same movie on both DVD9 and the BD rips, and I find the DVD9 pic cleaner. DVD9s are direct copies from the real deal, while the BD rips are, well, rips. You'll always lose something during rips.

I guess they will have to compress the video to lower resolution to fit in a DVD 9. So in summary better to just get the DVD9 unless you go for the actual BD's $$$

I tried before converting my 720p movie file to DVD format. The picture is far better than normal dvd purchase from store. I think it will make a difference.
