put the video on your hard drive.
Thats the easy way. (I ve done it 5-10 times that way.Due from bad rentals at Hollywood or crapbuster .The other program would couldnt complete 2 percent.Where anydvd was able to do the dvds no problem ?? )
Unfinalized dvds... Well my liteon burner will read them from the RCA like that. Cant speak

You can try
ISO Buster.To get the data you need. That program has saved me a number of dvds.
