Problem playing DVDs

Hi, I am a newbe to Linux and Mageia. I have intstalled version 7 (have previously used version 6 with same problem). I cannot play commercial DVDs. I have tried several video players. With VLC I do get a message that access to the file is denied. I thought his might be due to the DVD region, but both my DVD player and DVD are region 2 for Europe. After some research I feel it may be due to libdvdcss not being included in the softare. ( It is in Mint and Pinguy). If so could someone tell me how, in very simple terms I can rectify this?
I can confirm that the DVD do mount but do not play
