DVD+R contents not readable in WinXP

I have Pioneer DVR-108 which I think is a DVR-A08XLA
Firmware update to version 1.20B
It can read commercial title CD and DVD disc with no problem
It can read burn CD-R, CD-RW and DVD+RW disc with problem
It can not read any data or home made dvd I burn on DVD+R disc but I do have a 1 data disc that do load which is odd.
All disc where burn with Nero or Ulead DVD MovieFactory
All DVD+R disc I have work fine in other OS like Linux, Win98SE and Win2000 Pro with same DVD drive listed above.
In idea on what could be wrong in WinXP??
