I just bought the Philips DVD+RW/+R229K writer to make my own DVD's. Works great and is very easy.

But then the final test: playing the new DVD in my stand-alone player (Philips DVD-750):
The DVD does not play at all !!

Can anyone tell me what the solution is to be able to play DVD+RW and DVD+R on a Philips DVD-750.
The DVD+RW was burned using Sonic MyDVD on Windows XP, with a Philips DVD+RW disc and played on a Philips DVD-750 (firmware upgraded to 7.22)

Help me please !!
