I can't record with speeds minor of 6x or 8x !, and i really need write my dvds with 4x or 2x !.
In my town don't buy dvd+/-r or rw capable 4x or less

somebody know some technique or firmware for my burner to able 4x or 2x write speed?
Thanks in advance.
Note: I can burn with other dvd writers with the same discs in 4x or 2x, but my own not support this speeds.
