There is some arguement about that - most don't believe it is actually showing 1500 lines - but nobody can prove that one way or the other.

I thought it was much better looking than the XBR - but I have no idea how the 2 were tweaked.

No, because the Sony 34XBR910 has a much finer pitch HD CRT that can actually resolve 1400 horizontal pixels, the JVC's CRT is probably only around 850 horizontal. The 1500i is meaningless, its a cost savings measure nothing more. I think JVC messed up the numbers its probably 1050i (which is double the 525 lines). The finer pitch HD CRT (unique to the Sony XBRs) allows for the highest viewable resolution HD video compared to all current CRT sets.

Perhaps there is some advantage to doing 3/2 pulldown at 1500 rather than 1080..? Likewise, "Don't beat me up, i'm just asking..."

Glad to hear the JVC "looked much better than the XBR". The one 1500i I have been able to actually see had poor source material and was sitting on it's own. I saw the 34XBR510 and 910 side by side and the 910 beat the socks off the 510 in many ways. I also have no idea about how each was tweaked other than a respectable sales manager telling me they should be set similarly or appropriately.

At the GG, they had the XBR and the JVC sitting right next to each other, with the same HD loop feed. The Sony looked dull and unsharp compared to the JVC. I changed some settings on the JVC - visual mode, aspect ratio, etc - still looked better. I'm just one person, but it sure looked good to me :)

Are you sure that was the Sony 34XBR910 or was it the 510? The 34XBR910 I saw was very 'crystalline' in appearance (compared to the 510 sitting next to it). Also the 510 was much duller (grey film over the picture) than the 910.

What is 'GG'?

GG = Good Guys, a west coast chain selling home theater, home and car audio and video, and perhaps soon, computers since they were recently purchased by CompUSA. I purchased my new DirecTV HR10-250 HD TiVo at Good Guys, as have at least 1500 other folks (not all have been delivered yet).

There is a Good Guys web site that shares the name only--they do not offer the same products as the B&M stores except by coincidence.

It is really an amazing set, you will love it !! Smart move, once you have it, go back to some of the stores, and give the Sony's another look.
You will seriously wonder what all that hype is all about. :confused:

That may also be a Comcast problem, I am subscribed to Cablevision, and in all honesty, the SD, running through a Tivo, (another split) looks great.
I have also noticed, while watching SD, that it varies from program, to program. Even when I had the JVC analogue 36" set, some programming looked better than others, possibly the way the programming was originally recorded? I have watched some lousy quality movies, and when a commercial came on, it was crystal clear.
Fortunately, I have an extremely strong signal, you might want to have your signals checked, if they are borderline, Comcast should supply you with an amp, which would make a world of difference.

There is a Good Guys web site that shares the name only--they do not offer the same products as the B&M stores except by coincidence.
The Good Guys website is part of the GG B&M chain, and the site has links to their store locations, unless you're talking about another company that happens to go by the same name. Good Guys is almost a copy of Circuit City, only with shadier salesmen and tactics.

Yup - sure it was the XBR910, I checked.

Comcast is pretty crappy most of the time - and the Tivo replay is even worse... but I'm not so concerned about that. Everything that counts looks great. The guy had his meter with him when he installed the box and checked the signal, so I guess its ok or he would have done something about it...

Either way, I think its a great TV.

The JVC looks pretty sweet, and I say that having just bought a 30inch Sony, see I'm secure with my Sonyality.

Question on the scaling / interlacing. Since JVC claims to be showing everything at 1500i, what is the best input? My STB will do 720p or 1080i (and also 480p/i) - I have it set for 1080i for HD and 480i for non-HD. I can't seem to tell a difference with just brief glances if I change settings, so I guess it doesn't matter, but I'm just wondering about the theory behind it.

Is it better to feed as close to the 1500 resolution as possible, and interlaced so it doesn't have to de-interlace it? Thats kind of the way I was thinking, but not sure if I'm way off base.

Who says they're not? I've seen a number of posts about the great picture quality of the JVC. It's argueably one of the best TV brands but not a lot of people know this. Some years ago JVC routinely gave Sony a run for their money and they made fantastic TVs; right up there with Sony and Mitsubishi. Unfortunately it looks like JVC is no longer focusing on tube TVs - however their plasmas are very highly rated.

They use the same parts on most of there electronics though... Most of the time you can look at the product and swear its a panasonic but JVC name is smack on it.

you might as well say they're the same

Most of the pro Sony opinions I have read, are by people who have never even seen a JVC set. Most of the threads I have read regarding Sony, either pertain to problems, or calibration, why calibrate ?? If these sets are so good, what is there to improve??
I have seen the Sony line, amongst others, and I chose the JVC, right out of the box, no calibration needed. I am very picky when it comes to audio/video equipment, and in "my humble opinion", the JVC outshines them all.
It's only too bad, that the nameplates couldn't be taken off the sets, before they are put on the shelves, then form an opinion. Maybe then we wouldn't have a bunch of guys touting a set, that they overpaid for, and trying to justify why they paid so much, so they could sleep better at night........

After doing a little research I found out that Panasonic and JVC are owned by the same parent company.

Matsushita is the parent company of Panasonic and JVC.


I knew it!

Thanks for the research; they're being a subsidiary of Matsushita was news to me. I did some further reasearch too. Matsushita bought a major stake in JVC back in 1954 and apparently they now own 52 percent of JVC Corp. That said, JVC continues to operate as a separate business unit from the other Matsushita subs, with their own R&D and global manufacturing facilities. It's not just a matter of the same products being rebadged as either brand. I've owned several JVC products over the years and can assure you that my VCRs and TV are not rebadged Panasonics (and that my Panasonic TVs weren't JVCs either!).

There is no doubt that Sony makes excellent sets. In most comparisons I've made, Sony sets are clearly superior to other brands when it comes to clarity and accuracy in color balance... and the xbr's when properly set up and calibrated are truly stunning.

With that said, I have seen the JVC set with an hd feed in my brothers house and it also offers incredible performance. In fact, I've come to the conclusion that it is every bit the equal of the 910. You gotta give props to JVC, considering this television was their first entry into the hd widescreen market - they really nailed it. What a shame it's been discontinued.

I'm waiting to see if the price drops at Good Guys. If it dips to $1400 than I'll pick it up. If not, I'll wait and see what happens with the new sets from Panasonic and Toshiba.

I don't seem to be able to get my JVC remote to find codes for either my Samsung ST-360 STB or Sony SLV-770 VCR. Does someone have some positive experience along these lines?

I just got one of these from Good Guys over the weekend. Thanks to everyone who answered my questions about this set in other threads. So far I'm very pleased.

I took some time to set it up using AVIA yesterday and was very impressed by the result. I played the new Spiderman Superbit DVD (via 480i component from a Pioneer DVD player) and the picture was amazing. Sharp, clear, with great blacks and color. I never saw one deinterlacing or scaling artifact. It's hard to imagine that HD could look too much better. Theoretical arguments about 1500i aside, the end result is very good.

The picture from SD cable and Tivo varies a lot of course, but is generally acceptable. At least it looks smooth, no visible pixels watching from 6-8 feet. I don't yet have any high def sources to try except some Windows Media stuff. I will have to hookup my HTPC and try it out when I get a chance.

I set up the TheaterPro mode for viewing in a dark room. Here are my settings from AVIA if anyone wants to try them

TheaterPro Mode Settings

Tint +1
Color -4
Picture +16
Brightness -6
Detail -8 (usually called Sharpness)
Color Temp - Low (not sure if this has any effect in TheaterPro)
VSM - Off (Theater mode seems to turn to force this to Off)

When I first set the Color (saturation) using the color bars and blue filter I got a higher setting than -4, but the later RGB color test pattern indicated a 15% Red push which made flesh tones a bit too red. I backed Color down until it was only 5% which reduced the "too red" look. All in all the default settings on this set are not too bad, except of course the Picture (contrast/white level) is cranked up to the max out of the box and the default Detail (sharpness) setting of 0 has some ringing.

I plan to setup the Standard mode for daytime viewing since TheaterPro looks a little too dark in a bright room, but haven't had time to do it yet.

I tried some of the other test patterns on AVIA, in particular the cross hatch. The geometry is pretty good. I had some tilt which was easily corrected with the Tilt setting in user menu. There is some slight pincushion with the outer vertical lines bowing outwards. I see a slight horizontal misconvergence on the red. However, I never noticed any of this while watching the DVD. The set also has pretty significant overscan, about 5-7% (vertical and horizontal numbers are different).

So this set could probably benefit from a good professional or ISF calibration, but I could certainly be happy with the picture it has now. If I find anything of interest I will post it.
