DVD Rental Stores? (Doha)

Question:

Are there any DVD rental stores in Qatar...something similar to DVD Base in Lebanon or Blockbuster Inc. in the U.S. Are rental memberships possible and where? We have that all over Lebanon but it doesn't seem like it's available in Doha.

I've checked Virgin Megastore many times and many popular DVDs are 'out of stock'...what could be an alternative?
