What type of DVD disk does


What type of DVD disk does hollywood movies come on.  DVD+R DL or DVD-R DL ?  I noticed after looking at the size of some of the hollywood movies they are over 4.7 gig so it must be dual layer in order to hold more than single layer DVD.    I was looking at buying a new Sony – UBP-x800 4K Blu-Ray player but they said it can only read DVD-R Dual Layer Video VR (w/o CPRM) only .   So I am not sure if hollywood movies would play on that new Blu-Ray player.   I noticed when trying to order dual layer DVDs that DVD+R DL seems to be more available on the market if that means anything.  I am just guessing buy most DVD players probably support both DVD+R and DVD-R disks.  I am still not sure what VR (w/o CPRM) means.

Any thoughts you have would be appreciated.
