Can my Mac play HD DVD or Blu-Ray disks?

I have a 2ghz Macbook Pro and iMac I bought about a year ago and I’m not sure if they can play HD content. I’m still pretty unsure about all the HD details, etc. My optical drive stats are as follows:

Reads DVD: Yes
CD-Write: -R, -RW
DVD-Write: -R, -RW, +R, +R DL, +RW

And does the “DVD-Write: +R DL” mean I can burn dual layer content?
