Thanks for the info Peter, I've tried with Nero and the discs burned ok but they are not readable in the saturn (some cheap nasty ebay 99p jobbers)
Will buy some decent Verbatim Media and give it another go.
I'm using the Saturn on my little JVC LCD, the one I use for my Amiga's. Via RGB Scart the display is perfect, I might have a spare Scart lead here if you need one?
Speak to you soon about the switch
