Files compliance fails in DVD ripped with InstantCopy

[nomax]

I "ripped" a DVD (the whole DVD with extras and all) using InstantCopy, then converted the PID image to ISO with PID2ISO and extracted the ISO contents with Winrar.
Now, when I try to burn a DVD VIDEO in Nero it says that the DVD-Video files compliance test has failed. The error window shows these message:
Backup file "VTS_01_0.BUP" should be identical to "VTS_01_0.IFO"
Backup file "VTS_02_0.BUP" should be identical to "VTS_02_0.IFO"
... and it goes on like that up to VTS_07_0.
What does this error mean and how could I fix the problem?
Thanks!

You could try copying the .ifo files over the .bup files... all they are is backups of the .ifos anyways.

And I know a lot of you hate the command interface, but this is a perfect time to use it.
To copy all ifo's to their respective bup's open DOS Prompt, CD to the folder, and enter:
copy *.ifo *.bup /y

sometimes the command line interface is the BEST :)

Ah ha, thank you for your advices, I love the command line interface as my first PC had MSDOS 3.2 installed... talk about old-timers :)
