friends, i'm trying to rip battlestar galactica. i've ripped other movies just fine, however, every now and then i have to switch the ripper i'm using. sometimes it's vobcopy, dvdcopy in linux. somtimes dvdfab or dvddecrypter in windows. however, this battlestar galactica will not rip. almost none of the dvds will in the set. so my question is has anyone ever experienced this? known good dvds (that play in regular players) that won't rip? is there a particular brand of dvd player that you are using that works/rips everything? thanks for the info!
