On Monday I installed my new Hauppauge Nova T USB2. Vista has automatically chosen old drivers from 2005, it worked well with DVB Dream v1.4i. But yesterday new local channels began to broadcast in Paris, there were freezes on all my softwares, as a consequence I decided to update drivers : I have the latest ones (1.17.25082.0) and DVB Dream doesn't work anymore : it don't find any channel whereas I have no problem with other software and these new drivers.
No signal with DD

A few minutes later with PouchinTV software

What can I do ? I tried to install DD 1.4g, also 1.3c, with no result

Thank you very much.
