I have a pioneer ao4 dvd-r drive and have been making backups using Smart Ripper, Rempeg2, spruce up demo, and prassi primo dvd. since spruce up is the demo version, and no longer available to purchase, i'm unable to make dolby 5.1 backups, only 2 channel stereo.

I was wondering if anyone else out there is doing this, and what techniques and software they are using.

thanks
