DVDinfopro did not show media code?

I installed DVDinfopro and DVDidentifier in XP system. But both did not show my media code at all. Any idea?

I know MATRIX media does this.

Many (old) DVD writers can't check the media code on blank DVD+R/RW media so if the media code is not displayed you may need to burn something on the disc first.

I had a similar problem. I had my writer hooked up to a PCI Promise ATA133 IDE card. When hooked to this card using DVD identifier it would not show a media code of any DVD disk either + or -, burnt or blank . When the writer was hooked to the motherboard IDE slot DVD identifier would show the media code.
