Liteon1633 burns RITEK 4xdvd-rw @2x only?

hi my liteon 1633 firm BSOS burns ritek 4x dvd-rw at 2x only at maximum…
please any help appreciated…
i thought this drive supports 4x dvd-rw out of the box…it is stated on box…

thanks guys for help and suggestions

I checked the Omnipatcher Media Code Report for BS0S and this are the speeds BS0S uses for Ritek dvd-rw:
RitekW01 2x
RitekW04 2x
RitekW06 4x
It depends on the mediacode what speed is used. You can check what mediacode your disks are with DVD Identifier, KProbe, SmartBurn etc.
