DVD Burner not recognizing disks (HP DVD740e)

[qanda]This thread is about the HP DVD740e. Click here to see full specs[/qanda]Hello everyone, I am newly registered and need some help with my HP DVD burner 740 B. I just bought a Compaq Presario SR1103wm without a cd dvd drive. I am currently running XP Home. I installed my dvd burner and everything seemed fine except it will not recognize any disk I put in it. I used my nero info tool which recognizes everything, still no go.

I had a similar problem before when I went from XP Home to Windows 2000 Pro and then back to XP Home. I was able to fix it by searching forums on a high speed connection, I am on dial up now. The thread I followed informed by deleting I believe a vxd registry. Does anyone have any advice for me with regards to this error?

Does it not recognize any media, or just not blank media? For example, can it read data discs and movie discs?
