I have run into some disagreement when it comes to BD/DVD combos, and I’d like to discuss this.

The parent profile should reflect the Blu-ray. That’s something that everyone seems to agree on, me included. But there is a catch. When you check both BD and DVD in the profile, you unlock two fields that are only relevant to DVDs; “16 x 9 Enhanced” and “NTSC / PAL”.

I would like to think that most of us would agree that it doesn’t make sense to leave NTSC checked if the DVD is actually PAL. For Blu-ray, the choice should be “N/A (not applicable)”, but there is no such choice, so selecting the choice that actually applies to the DVD makes the most sense.

Well, even though the “16 x 9 Enhanced” info is a checkbox, it also has two distinct meanings; anamorphic or non-anamorphic widescreen. And just like in the NTSC/PAL case, there is no third choice. Leaving it unchecked does not equal “not applicable”. It means “non-anamorphic”.

So, just like NTSC/PAL, it makes sense to select the choice that actually applies to the DVD. The fact that a child profile is optional just reinforces this view.

However several votes in a recent submission goes against this. This seems illogical to me.
Any views on this?

Agree as well, and for the same reason.

I agree with the above three comments. It pertains to the DVD only, and belongs in its child profile only. It has no meaning for the Blu-ray parent.

But there is no way to keep it in the child profile only. Just like NTSC/PAL it is there, like it or not. The fact that the user interface is a checkbox rather than two radio buttons doesn't alter the fact that it is a control that has two states, and both states have a meaning. True, these states only have a meaning to the DVD, but keeping it unchecked is no more correct than keeping it checked as regards the blu-ray.

And maybe I am misinterpreting them, but I thought that gardibolt and dee1959jay were agreeing with me?

I have hundreds of Blu-ray + DVD "Combos" in my collection, and I never see contributors enter it that way. In fact, I can't really even remember ever having seen it that way in a profile.

The "16x9 Enhanced" box is not even an option for Blu-ray only profiles, and it does not default with it checked when a DVD Combo is created. The DVD child profile is specifically for specification data such as this difference. We may as well enter other DVD-only details in the Blu-ray parent if the DVD's child profile has no purpose.

I read the rules on it here as thus:

Use the check boxes as follows:

16 x 9 Enhanced | DVDs with a widescreen presentation that is Anamorphic, often listed as "Enhanced for 16x9 Televisions".

The rules specifically do not even mention Blu-rays, but DVD's only for that Video Format option.

Sets containing the same film on multiple media types (such as a Blu-ray/DVD combo pack) are to be entered as a normal profile for the main media type (Blu-ray in this example), with all included media types checked. A combo which includes HD media (HD-DVD, Blu-ray) as well as DVD should use the details from the HD media in the main profile. However, you may add an additional profile by Disc ID for the DVD content and add this profile to the Box Set contents for the Blu-ray profile.

A DVD is not HD media.

Yes, the bottom line is that it's a design flaw in the program.

If Ken would be so kind to fix this in the upcoming program update for UHD Blu-ray, then this whole discussion becomes void.

Yet, you would happily have conflicting information regarding anamorphic/non-anamorphic. Unchecked in the parent means non-anamorphic. Checked in the child means anamorphic. That doesn't make any sense to me.

I don't agree there. Other things like a DVD's region coding is not (and cannot) be added in a Blu-ray parent profile. That is the whole need for DVD child profiles to be attached in combo packs...to add that specific data.

I am not sure just what in the text that you quoted that you don't agree with? I never claimed that the parent profile can contain all DVD data. There are lots of things that can be different between the blu-ray and the DVD. I never disputed the fact that you need a child profile in order to have all the data about the DVD. What I am saying is that there is some DVD data in the parent profile, and it doesn't make sense to have that data conflict with the data in the child profile.

Since the DVD data is irrelevant for the Blu-ray profile it doesn't really matter what you enter or don't enter in those fields in the parent profile since that is not our source of information for the DVD data. So making any profile changes to these fields in the parent profile is pointless and should be avoided imho. But I agree that it is a design flaw of the program but that is not for us to try and correct. Just ignore those fields for now.

We're not talking about a Blu-ray profile as some posters keep asserting, but a Blu-ray/DVD combo. A combo profile contains more fields than a Blu-ray profile and those additional fields pertain to the DVD part of the package. Why would anyone prefer incorrect data to correct data in those fields?

The DVD child profile is optional. I'm sure I'm not the only user who doesn't bother with them. Having some DVD info in the combo profile is a good thing and not at all a design flaw.

I'm with GSyren.
