DVDs won't load
My disk drive won't load DVD. I insert the DVD, it sounds like it starts and it clicks, then it ejects the DVD. It seems to accept CD's but not DVD. I have tried running a DVD that I have used before and they don't work anymore. I have also tried the below without any success.
-Cleaning with a lens cleaner
-Cleaning with canned air
-Reseting the SMC
-Reseting the Reset NVRAM/PRAM
-Running the Apple diagnostics
-Deleting com.apple.finder.plist and com.apple.sidebarlists.plist in preferences
For reference, I have a mid 2012 MacBook Pro running macOS Sierra v10.12.6.
