CD player won't play any CDs burned on my mac

I'm trying to burn some CDs to play on my 1997 CD player but so far no luck I first burned mp3s on it and then I realized old CD players don't play mp3s Then I burned .wav files as an audio CD but I used DVD-R because I ran out of CD-R It still won't work Using Macbook Pro 2021 What am I doing wrong? Is there a workaround?
