Burn after print
If anybody is interested, for info:
I burned onto a DVD which had been printed on. Whilst it might not be recommended, it works.
The DVDs say they are PioData(?) which I was told by the shop are Ritek dye (anybody confirm), burner is Pioneer 107, printer is Epson Photo R200, s/w is InterVideo DVD Copy 2 after ripping with DVD Decrypter (using the easiest tutorial I could find on this site).
Anyway, thanks for the input chaps.
