DVD Combo Toshiba D-VR610

Question

Good Morning
I wish buy a DVD combo in USA, but I have a some doubt. I'm from Brazil and here this kind of product isn't avaliable. My doubts are:
1- May I play any kind of DVD in this product ( DVD from all regions )?
2- The VCR play NTSC/PAL-M tapes?

I tried find this product here but the companies stoped the production.
