Had a similar situation on a contribution i was making (original was a flipper and re-release was a single sided dual layer disc) i had received "No" votes so i raised a support ticket and was informed by Invelos that the contribution was perfectly valid

Did you remove the side B disc ID

Yes

As far as I understood this Disc-ID "problem", the Disc-IDs are "additional".
Means: even though the original Disc-IDs don't show up in the profile (anymore), they are still associated with the profile, so no real harm done.
The problem arises if there are other differences (e.g. Features) and someone starts to contribute the different features because they now match the currently prominent DiscID.

Solution: The original DiscIDs should remain in the "visible" part of the profile, while the additional (ReRelease) IDs disappear in the depths of the database and remain there until they are finally of some (future) use.

EDIT:
For those that stated that contributions like in TheMadMartian's example would violate the rules, here's a little reminder:

Quote:
If your Disc ID differs from the Disc ID in the main database, you may change it and re-contribute it. All Disc IDs are stored in the main database and are used for disc identification within DVD Profiler.

The only condition for a DiscID contribution is that is has to differ from the existing. There are no other restrictions, so the contribution would be completely rule conform.

Thanks to ninehours and Katatonia for the information, I will adjust my vote accordingly.

what is stopping anyone from changing it back again...

Nothing, when i change a disc ID i copy and paste the IDs in my notes to stop ping ponging of the data but people just ignore them and still re-contribute the old disc IDs even though it is not needed (there's one at the moment for "The Quatermass Xperiment"

I was directed to this topic, as I am another no-voter in this particular case (yes, the BSG Miniseries).

First off, I also got the second variant (two discs, instead of one two-sided disc), so basically I would be fine with the change. But I really think that people miss the point: the Disc IDs have not changed at all. Again from the Contribution Rules:

In this case there is no other Disc ID, it's a simple packaging variant/change. It's nothing other, than the change from a first release Digipak to a re-release Keep Case or any Cover change. Universal re-released many of their TV-on-DVD releases on single-sided disc, after customers complained about the double-sided (DVD-18) becoming unreadable. But they didn't change the discs, they just broke them down onto two DVD-9. That's a packaging change, not a case of an alternate Disc ID. So in this case: No, we don't track this kind of change, according to the rules.

But: Yes, we would track the change, if a Disc ID would have changed. This is always the case when merging a "Flipper" (DVD-10) onto a DVD-9, you will get another Disc ID.

BTW, I haven't voted in the poll, nor will I, because it simply lacks the correct answer: it depends on the Disc ID.

If it's the same disc ID as side b of the old flipper discs, maybe just attach a note to an audit mentioning you have a re-issue with just the FS side, same disc ID as side b of existing. Then the powers hat be can note it for the DB, and those who have the old flippers won't have to re-sub the proper first disc ID's.

I didn't compare the disc IDs to see if they were different.  To be honest, the thought never even crossed my mind.
