i have this player and i used to use a ricoh mp5125a with datawrite dvd+r discs with the bit set to dvd-rom. this worked until i recently bought a pioneer a06, now i cant seem to set the book type anymore and the backups show up as no disc and wont play in the dvd player. should i buy some dvd-r discs and use those or what settings/software should i try, i currently use nero's dvdvideo mode not udf/iso.
