ProgDVB keeps crashing

#1
Hi,

I recently purchased a Hauppauge WinTV NOVA-HD-S2 that I use on a Windows Vista PC. I deceided to use ProgDVB as a software for its comfort with remote control and a true STB behaviour in full screen mode. But I have one problem, everytime I launch ProgDVB I get a message that it crashed during last use and I have to reset settings. This is a problem because everytime I have to adjust video audio settings.

Can anyone tell me what to do to solve this problem ?

My PC information

Intel Core 2 CPU @ 4400 2200 GHz
Nvidia GeForce 8500 GT

Thanks in advance
