NEC 3500 + Ritek R02 / RICOHJPNR01

Hello,

I recently bought the NEC 3500.
I had some old DVD from Ritek R02, but these blank DVD don’t work properly.
And i still have more than 25 DVD like that.

I think that this is coming from the firmware that doesn’t support Ritek media.(Or am I wrong?)

I have the last official firmware v2.16

Is there some hacked firmware that could resolve this problem?

If not what are the best media for this DVD burner?

Thanks

Ritek 05 is ok, for 02 try the 2.27 firmware - seems better to me.
