DVDXcopy works very well for me.
I am not rippingand burning at the same time.
With DvdXCopy you et the same audio and video of the original not like many others that shrink and compress to fit on one dvd.
Backups should be high quality, high qulaity to me is an exact copy even if its 2 discs.
The issue her may be both this dvd burner, and media, NOT devxcopy, me thinks.
I have been using dvdxcopy on 2 other drives (both dvd burners) and the ability of ripping with one and when thats done the burn start on the second dvd burner a few seconds after the rip ends. You dont have to be around to feed in another dvd.
Its worked well for months for me.
When the new NEC 2500A was added for its faster burn times, I foound that after the rip ends the NEC would not start up automatically like three other burners do reliably.
IT just sits there incactive forever. Eventually the systems will hang and have to be cold booted.
NOW if I dont use RITEK or Princo DVD-r and use a HP DVD+RW it works!!!
I can burn low quality -R media via Nero and Roxio and dvdinfopro etc....
Its just that with the NEC it will not burn to the cheap stuff i have been using formonths now.
THe rub here is NOT DVDXCOPY but NEC...a cheap fast drive that needs expensive media to write fast!!!!.
