Sony Dvd Rw Dw-q28a problem

my Sony write dvds +r or -r without any problem BUT it is impossible to write DVDs REWRITERS (+r or -r is the same, not WRITE!) The programs like Nero, Cool CD burner, Etc hangs when we try to write any DVD -RW

What happen? Please Help me!

Actually the Firmware is KYS3, but I don´t thinks that we need to update it.

Please post more inof, a ligfile, also the exact brand, name & rating of the RW media.

KYS4 is available for your drive. It wouldn’t hurt to update anyway :).
