python and dbus - beginner seeking some help

[bob]

Hello,

First of all, does anyone know whether dbus will allow be to do 3 things:

1.  query whether or not there is a dvd drive.
2.  query whether or not there is a blank disc in it.
3.  query what it's capacity is.

If I'm barking up the wrong tree, what should I be considering instead ?

If I am thinking along the right lines, then I'd be grateful for any links
to any guides or tutorials relating to dbus. I have tried looking and
found nothing uesful yet, and I will continue to do so, but I was hoping
someone could help.

Thanks for reading :-)
