singular DVD, plural DVDs (digital versatile discs)
DVD is a French equivalent of the English word "DVDs." The masculine noun takes one form in French whereby the singular and the plural respectively are differentiated by the masculine singular definite article le, as in le DVD, and by the masculine plural definite article les, as in les DVD. The pronunciation will be "luh dey-vey-dey" in the singular and "ley dey-vey-dey" in the plural in French.
For one DVD, use the singular possessive form 'the DVD's case'. For two or more DVDs, use the plural possessive form, 'the DVDs' case'.

The apostrophe is only used for possessive or to indicate missing letters, as in "it is" -> "it's", or "can not" -> "can't" Wiktionary.org/ does not have one noun that I could see that had a plural created by adding "'s", with the exception of "diva's" which I think can be contested. The same goes for abbreviations like CD and DVD -> CDs and DVDs. NO APOSTROPHE!
