My PC is DVD-R. I have had no problems playing films produced via my PC, on any DVD player (yet).
I have played my DVD films on 4 different 'domestic' players. None of which cost a great deal of cash.
I think you should check, when buying, whether the DVD Player will play recordable disks.
This is the player i have just bought for my Daughter.click here As you can see it claims to play many different formats for very little money. I've yet to find a problem with it.
