Best cheapish DVD+R media for stock 1300a

I have a friend who is making backups of his DVDs on a NEC 1300a. Having done a quality scan with nero6 for him, I have confirmed that the discs are full of errors. This was expected as the movies normaly fail sometime during playback.

What would be a good cheap well known brand to use?
I do not know what filmware is being used but it would be the original and would have to stay that way.
Any and all advice would be great

Your friend should upgrade to latest firmware.

If he can’t burn RICOHJPN R01 with better result than above, there no need to try other media, before he for sure is using latest firmware.
