Phillips 980 jerky when reading PC written disks

[Kera]

I have made a DVD+R and DVD+RW of my home video footage using an HP DVD200e DVD writer and Pinnacles Studio 8 software on my Laptop. Both disks play OK at the start of the footage, but become jerky towards the end of the disk on teh Phillips 980.

I can play the DVD+R all the way through and it is smooth on my old Samsung 511 DVD player.

Any ideas of how to fix this issue with the Phillips 890?
