Bitsetting question

I have a NEC2500 and am using this firmware: HP520n v.2.21 (2500R221 @

I used DVDInfo v3.07 to change the bitsetting of my Infiniti DVD+RW 4x to DVD-ROM but in Nero CD-Speed and DVDInfoPro’s Error Test the media type is still DVD+RW but everywhere else its DVD-ROM.

Is this correct?

I’m using the latest Nero too and use it to burn most of my stuff.

Yes media type does not equal booktype.
Many programs can still recognize that a disc is a DVD+RW even with the booktype changed.
