DVD-R play on PS2 but not on DVD Player..!

Asking all advanced profecional to explain this pls. I had a DVD-R that play on PS2 and have copied it to DVD+R on Pioner DVD Writer Using DVD Fab Express. But the new copy still doesnt play on the DVD player (Philips FW-D5 all in one stereo/DVD Player). Is ther any change in format needed? the curent files in VOB+ BUP+IFO format.

The session writen as UDF/ISO 9660 (Mode 1).
