I burned a couple DVD movies on this media:
RICOHJPN/R01/002 4x +R
MKM/A02/na 4x +RW
They both play on my Panasonic player, however while the +RW does play on my friend's Sanyo 6040, the +R does not, which struck me as odd as I would more expect the reverse. So my question is whether this is likely a format compatability or a specific media incompatability and if the latter which does work? The videohelp.com database was unhelpful.
