scarface backup?

[d0thedew87]

well i've had many many many successful backups of over 25 movies, but when i try and back scarface up, it won't let me do the 2nd disk...i'm not sure what's going on. it says "please insert blank media" or something to that extent, so i retry different blank media and it still doesn't work...just to make sure it wasn't dvdxcopy that was flipping out i recopied platoon, and that worked fine, it only seems to be w/ scarface...any ideas?

thanx

oh yea:
dvdxcopy 1.4.1
sony dru-500a
liteon 16X dvd-rom
