Advice re AWA portable DVD - DVD-R vs DVD+R

[spanish72]

Am hoping someone out there can help me in regard to our portable DVD Player AWA 8".
We have been trying to play DVD+R but am not having much joy, am I doing something wrong or do they prefer DVD-R?
Thanks

Could be the brand.
What brand are you using?
Also, if your burner can bookmark the DVD+R discs as DVD-ROM, they might work.
All depends on the unit though.
(Hopefully someone with first hand knowledge of your unit can comment)
