Missing video files, can't burn in Nero. Help?

[kid apathetic]

hmm, I ripped 2 DVDs and I got errors when I tried to burn either of them.

(the former is for my first dvd and the latter for the second dvd)

What are these missing files and is there anything I can do to recreate them from what I have(I assume everything else is in order because I have 4 gigs-4.5 gigs of files on each of them and I can view the .VOB files in powerdvd) or am I screwed? Unfortunately I no longer have access to the DVDs so re-ripping them is not an option. thanks in advance for the help.

If you don't have the discs any more, then what you are doing could well be illegal. Beware. Since I got told off by a moderator who's clearly been buying his meds from spammers recently for "jumping on threads", I'll answer it this time.

Just make a copy of the IFO files you have got and rename them .BUP and you should be fine.
