Problems using Hauppauge WinTV-dual HD

I would like to use my Hauppauge WinTV-dual HD and the device is properly recogniced, but PorgDVB is unable to find any channels.

The Problem seems to be, that the symbol rate has to be set multiplied with 1000.
Instead of 6900 it needs a setting of 6900000.

I found that hint in the DVBViewer forum, they have an xml setting SRx1000 that can be set to 1 to make the device work.

Any idea how i can achieve this with ProgDVB?
