I just received my HR20-700 and got a plasma Panasonic 42". I have read when you set the HR20 to NATIVE it selects the format the program you are watching to whatever the show is set at. When I first got the HR20, I had it on native, but it would kick off then kick back on after a bit. It got annoying, so I turned the native off. No more problems, but it stays in the 1080i format. Should I reset the HR20 to native to get the best picture available?

Thanks for all help in advance, I'm learning a lot and this HD stuff is new to me, but after watching HD, it's the ONLY way to go!

It all depends on what your TV can handle.

If the best true resolution your TV can do is 720p, then leave it at 720p, as your TV is just going to take the 1080i and knock it down.

If your TV can do 1080i, then you will have to decided which has a better scaller.... Your TV or the HR20.
As one of those two is going to need to take a 720p and upscale it to 1080i.

If the TV is better... leave the unit on native resolution
If the HR20 is better... fix the resolution to 1080i

I have the Panasonic TH-42PX600U. It has an awesome picture with the OTA antenna. I guess I'll have to compare the differences between the formats when I get home. Thanks for everything, Earl. You've been a great help on many of the issues I've confronted.

THANKS AGAIN!!

I hope you report your findings. I have the same TV and would like to hear what you find.

So exactly how good is the HR20's scaler? Even when you read reviews of displays they are very vague when discussing scalers. How many scaler mfgrs are there and who does "D" use?

Portland...,
I'll do it. And please let me know if you have any suggestions that might help me. I found some settings for the TH-42PX600U that improved the picture immediately. I'm trying to find where I got them, I've got the hard copy at home. I'll let you know. Check back here later.

Portland...,
I found a great review and it has settings, suggestions etc. on the TH-42PX600u. Go to plasmabuyingguide.com and search "TH-PX42600u". I haven't posted enough to put the link in here.

When I use native mode it takes 8-9 seconds before I get a picture. The tv goes black for that long until a picture returns. Is this normal for native mode in all HD receivers or is it just a bug with the HR20? If it is a bug, will it ever get fixed?

I'd love to use native mode rather than scrolling thru all the formats but this delay is killing me.

I had the same problem. I haven't checked to see if there has been a fix put out yet. I turned the native off and set the HR20 to 1080i. Maybe there's a better picture than that, but it's perty dern good as it is.

I don't how long the HR20 takes to change(as I have a Dishnetwork setup), but I know my TV takes about 1-2 seconds to change when it's fed a different format signal.

I froze a movie on one of the 1080i channels and cycled my Panny 32LX60 LCD set thru the resolutions, and definitely saw a little more detail when the HR20 was set on 1080i and the TV did the scaling, even tho it is a 720p display.

I have to leave mine off Native as my wife would not like the delay.

Now I have to compare a 720p, with the HR20 set to 1080i.

I have the Panny TH-50PX600U and still is farily new. Probably only have 20 hours on it so I have all the settings at 0 per Panasonic's recommendation to allow "break-in" for the first 100 hours, which probably will take me 1 year.

That begin said, I had my HR-20 on native and it does take a bit to change so I just left on 720p. The long standing arguement has always been what is better 720p or 1080i. We could go on forever and get nowhere. To be honest really. I can't tell the difference but I am no professional by any means.

I know ESPN broadcasts in 720p and I think my Chicago locals do as well but what do I know. Of course my TV supports 1080i but don't ever know what to leave the res at 720p or 1080i.

I have a 720p plasma, Samsung HP-S5053, and IMO sending a D* 1080i HD signal to it, produces a better picture than having the HR-20 scale to 720p. YMMV

How do you go about "setting the HR20 to 1080i?"

I have the Sharp Aquos 1080p 42 in. I don't have HD service as of yet (few more days until the dish is installed), but I do have the box connected via HDMI. So according to the TV input - when the box is on Native standard def is 480i, with native off it looks like it's up-converting to 480p.

Can standard def channels upconvert any higher? Should they?

You can cycle through the format by pushing the format button on the remote. You also need to tell the HR20 what format your TV accepts. I believe it's Menu/Setup/Display? Somewhere in there you have to select the format you want (480i/p, 720p, 1080i) and turn off Native. I'd check but mine is unplugged for the moment.

SD can be upconverted using the HR20 if Native is set to off, but you have to tell it what foramt your TV accepts then you can select the format that looks best on your TV. You might find that your TV does a better job with SD if you feed it 480i, but it has to be selected as an option with the other formats. From your post it sounds like the only option selected when Natice is off is 480p. Have you tried the format button on the remote yet?

I have always wondered this as well even though in my testing on a few of my friends sets I find no discernable difference between the 2 settings. I have only had my set for 2 weeks and it is a Vizio 42" LCD that displays 720p. The picture looks astounding in HD at either setting. Now I do not have my HR20 yet due to the demand for the unit so I have not been able to test this on my own tv. But in my 2 weeks of watching HD through comcrap basic cable feed the pic looks pretty damn even to me. I think that the difference will be more noticable in larger TV's. I think that I will be pissed with the delay in changing formats so I will probably set my hr20 to 720p only.

There are some things that have been missed in this thread though that I will point out. If your tv displays 720p it will be converting everything to that format anyways. So my point is if you set your hr20 to display all channels in 1080i then you are going to be taking a 720 progressive scan pic (from channels that are b-casting in this format) and making it interlaced and then your tv is going to be taking the 1080i and de-interlacing it back to 720p to display it on your set. In my mind I cant see how all of these changes can do anything positive to a feed. But, I'm not sure if you can set the hr20 to display each feed independantly as I don't have mine yet.

I mean if you can set the hr to output 720p when it is on FOX lets say, and 1080i on NBC then that would be ideal if you are noticing a difference between the settings that is. I don't think this would cause to much of a hiccup as compared to displaying ALL formats in their native format. My tv has no delay when changing channels from a 720 to a 1080 pic. I believe the several second delays that are happening on peoples sets are when the feed is going from hd to sd and vice versa.
