What counts actual DVDR600 VR

Hello,

I have a Phillips DVDR 500VR and a Phillips DVDR 3554H both of which work well. However, when I go to add these items to my profile they are not listed. The list shows equipment with numbers on either side of mine but none that match.

Anyone have any insight into this, i.e., are they so ill thought of that they are not considered useful?

Thanks,
Kagnewmick
