I have a question regarding screen ratios. If the back cover says 16/9, which aspect ration should I put in the database then?

1.78:1 or 1.85:1 ?

Case in point: I have both Death Note movies (Japanese Blu-ray disc) and the back of the cover only states 16/9. When played on my HDTV, the picture fills up the entire screen (no black bars)

For now I have inputed them as 1.78:1 but I see that the Kitaro Movie (which also fills up the screen) is in the database as 1.85:1.

If all it says is 16x9, then it is 1.78:1 as that is what the math works out to.

Often times 16/9 is used in lieu of anamorphic or widescreen encoding.  You could have 16/9 and still have 2.35:1 ratio or even 1.66:1 with side pillar bars.

As far as difference between 1.78 and 1.85, if your TV has overscan (most do), you may not be able see any difference.  On displays with no overscan, 1.85 movies have a thin black lines above and below the picture.

16x9 = Anamorphic. Means it's enhanced for widescreen T.V.'s which have a 1.78:1 aspect ratio.

But that has ABSOLUTELY NOTHING to do with the ratio of the film. It can be anything from 1.78 to 2.40. You need to use a player (VLC Player is freeware) and an image editing program to measure the ACTUAL aspect ratio.

Too many people don't do this, they just go by what they can find on the jacket, which is often times WRONG.

A very specific question was asked and I answered it.  If the person asking the question had a player and an image editing program, he wouldn't have asked the question.  In addition, none of that is needed to contribute.  Copying the data from the jacket is prefectly fine.

Plus, while I have seen instances of the back cover being incorrect in regards to the aspect ratio, I don't see it as being "often" wrong.

Using the jacket is fine unless he is replacing verified data. Movieman you have no idea how often the jackets are wrong on technical issues including AR, far more often than they should be.

All I'm saying is the times I've looked, I haven't seen that many. I was only objecting to the term "often wrong" which would make it seem like well over half. I know there are incorrect AR's I've seen a few from Warner). And for the record, I normally do not go by the back cover since I can look for myself (the only difficult part comes determining 2.35 vs. 2.40).

Disney and a few others seem to be using 1.75:1 with tiny black bars on the sides for their anamorphic discs. Dunno why... And then we have 1.66:1 of course, but those are easy to detect. But then some are more like 1.55:1, more commonly referred to as 14:9. Again not a big problem, but I wish they would stick to ONE standard.

I have found that about 80% of the DVD's in my collection have incorrrectly stated aspect ratios on the back cover. They might say 2.20 and it turns out to be 2.05, or 1.78 and it turns out to be 1.82. I would definitely call that often.

For this reason, I don't think it should be allowed to take the aspect ratio from the back cover. You can't add the disc ID without a DVD drive. And if you have a DVD drive, there is absolutely no reason why you can't run VLC Player and IrfanView or Gimp (all 100% freeware) to check to see what the actual aspect ratio is.

To me this is like taking the spelling of credits from the back cover over what is in the end credits.

I have to disagree.  Nobody should have to add extra software to their computer in order to make a contribution.  And to me, your analogy just doesn't fit.  We are required to use the spelling in the end credits, so using credits from the back cover isn't even an option.

I agree with you but, for initial contributions or adding missing data, the case should be enough.

Your discs may have been from a different transfer to my DVD, but my Death Note films are both 16:9. I believe they were originally made for television, so that would make sense to use the whole screen.
I don't have the Kitaro Movie so can't check that. It's possible that your TV has overscan so you simply can't see the black bars, or it's a mistake on the profile/cover.

And yet probably 70% in my collection are probably correct. If I were to randomly pull 20 DVDs from my shelves that have AR listed on the back, I doubt half would be incorrect. As I said, it happens. But whatever, not really worth debating over as I try to document any changes with the AR.

Like Unicus said, upon initial contribution the back case is fine. If you're going to make a change, then it should be documented on exactly how you came to it.
