Ella Enchanted and Hoodwinked DVDs - skipping (Corsham)

I bought these but they skipped when played in my dvd player (a PS4) and they were replaced by the seller. The discs don't look damaged (see photos) so before throwing them out I thought I would offer them in case anyone wanted to try in a proper dvd player - or had one of those refinishing kits you used to be able to get to try cleaning them first.
