Ripping Reference Recordings HRX Discs


Hi,
I'm trying to rip my HRX discs to my server for playback on the PS Audio PWD with Bridge. So far I've tried using dbPoweramp, J River, and just simply copying the files via Windows 7 to my server without any luck. dbPoweramp doesn't seem to recognize the files even though they are wav format. J River tries to rip them then goes eventually to a blank screen, and copying through Windows times out and nothing transfers. (If the files did copy, I can't find them.) Any help or insights would be great.
Thanks,
Steve
