ProgDVB 6.05 and file filtergraph xgr

#1
As a object, if i have a file .xgr where i put it? Which folder?

Why i've using nVIDIA Purevideo and work only video codec but not the audio codec?
With DVBDream and DVBViewer work twice!
And if i right-click-> decoder options on purevideo icon in system tray, ProDVB crash (not with DVBDream and DVBViewer).
