My Blu Ray Player stopped playing DVD+Rs HELP!?

My Blu Ray player, for some reason, stopped playing DVD+Rs. It plays DVDs and Blu-Rays okay, and other DVD+Rs I've burned in the past, but this batch of DVD+Rs it just doesn't play well if at all. It just started with this latest batch of DVD+Rs, some will skip or freeze, some will say that there's a disc error and it won't play at all but it plays just fine on my two computers and DVD player. My Blu-ray player is a Magnavox it was bought over a year ago at Wal-mart for $70 bucks or so I think. Someone please help!
