u/Big-Note-508

I read many discussions about Wii's DVD playing compatibility, and I concluded that most Wiis can't play DVDs, I find it weird because I previously assumed that a Wii can play DVD normally by default, I have several Wiis from different regions and they all play DVDs just fine and can load the DVD menu like any DVD player (via WMC), are my Wiis ancient revisions ? am I lucky ? (iS iT RaRe ?) (I tried DVDs from Region 1 & 2)
