Em-dashes are still used widely in the US.

That said, though, it's good to double check, as I've seen hyphens, em-dashes and en-dashes on various descriptions. It depends more on the editor than the correct usage.

Yup, I see Em-dashes utilized all the time on releases here. Certain DVD studios use them more than others...

I just want to give you all a heads-up warning that many of you replace en-dashes (–) for em-dashes (—) in e.g. overviews.
I notice the buttons are switched around in DVD Profiler.
En-dashes are to be separated from regular hyphens; "-".
Em-dashes are almost never used anywhere.

Side notes:
On your keyboard, you can make an en-dash like this: alt+0150.
Em-dashes are made by inputting alt+0151.
In a program like MS Word you normally make an en-dash by pressing Ctrl and the minus sign on the numeric keyboard.

See what I put in bold....

I just double checked the buttons in the program... they work correctly.

About the buttons I didn't mean they give the wrong output...
Just that it looks to me like they switched places in an update or something.

Regardless of which, I live in a country where grammar matters.
Hyphens and en-/em-dashes are distinguished so to me it looks really bad with em-dashes. It looks "alien".

Why not use the common sense and compare the length of the hyphens in the text to be copied and in the program?
-/–/—

There is an obvious difference between the short hyphen and the almost grotesque em-dash.
It's to me as easy as that.
I mean, we don't all live in the U.S. now do we?
(Fortunately.)

And if this is a local matter, the program should translate em-dashes to en-dashes. I don't want an em-dash in my database if that's not what I see on the covers.
Or we could as well use —— whenever we see a hyphen.

And for the record, I haven't seen this many em-dashes being contributed since I first started using this program. Also, at first there was no other option other than a regular hyphen.
I think you should stick to some international standard or keep it local.

But again, I think it's easy to distinguish between the lengths of the hyphens just by looking at them.

Oh well. I predict this debate will lead nowhere, as usual.

Generally it is easy.  If i see an em-dash that's what i submit.  If it is an en-dash i submit that.  Easy!

There is not an international standard when it comes to dashes. Obviously.

Maybe I'm too dumb to see it.

But where is the difference between a hyphen, an em-dash and an en-dash (except for the key-combinations) and how do I verify which to use if only one of them is present?

Don't take it too serious.

The entire tone of the post seemed a bit condescending so I may have read more into it than I should have.

True enough...we do have a lot of empty space, right in the middle, but I don't think it would fit everybody...though it would do away with the need for region free players.
