When you encounter a DVD/BD that is not already in the database, it's a good idea to check if some version of the title exists in another locality and/or region. If it does, you can base your new profile on the existing one. This is sometimes referred to as "cloning" an existing profile.
When contributing to the main database it's a good idea to include the UPC/EAN and Locality of the profile you cloned, as well as mention which fields have been altered to fit with your version of the film.
| UPC/EAN LOCALITY | without changing at least one of those two, all changes you make are to the original profile |
| REGION | if necessary, make sure to change it to the new region |
| RATING | if your locality has different ratings than the release you're changing |
| RUNNING TIME | may be different |
| EDITION | will probably be different |
| RELEASE DATE | your release may or may not be different |
| SRP | make sure currency matches locality (SRP is the Suggested Retail Price price on release day) |
| CASE/SLIP | may be different |
| STUDIOS | sometimes in different geographical areas the studios (or distributing studio) may be different |
| VIDEO | may need to change from NTSC to PAL or vice versa (watch out for differences in aspect ratio as well) |
| AUDIO | audio & subtitles will probably be different too |
| OVERVIEW | may be different, even in releases from countries with the same language |
| DISCID | will definitely be different if change of region, may be same within region |
| COVERS | will most often be different if change of region, may be same within a region |
| FEATURES | will most likely be different |
| SUBTITLES | will most likely be different |
| EASTER EGGS | will most likely be different |
| MEDIA TYPE | if you've changed a DVD to Blu-ray or HD DVD (or vice versa) you'll need to change the media type. |
