I'm trying to find a suitable brand of blank DVD-R disc that will
successfully record on a Pioneer DVR-720 DVD recorder.
I have used 4x speed DVD discs in the past but now that many DVD-R
discs are 8x speed and faster I have a problem when the recorder tried
to write at 8x speed as the recorder will try to write at the fastest
speed. Excel DVD-R 8x discs don't seem to work on this DVD recorder.

Hoping for a reply.

Regards Brian
