Do Island DVDs work on PS2 player?

Im thinking about getting a couple of the Rodrigo Medeiros DVDs, but I only have a PS2 and I dont know if they will play because they are DVDR. ANyone know for sure if they will. Also, if anyone could tell me which are the top 2 dvds out of the set, thatd be cool.

I believe they will play on a PS2. My favorite are the closed guard
and open guard. Both are loaded with a lot of content.

They work on my PS2, and at @ $17 each, they work on my wallet much better than most other instructionals as well.
