CopyToDVD: BUP/IFO error messages; should I be concerned?

[supatrupa]

Sometimes when I burn a created image from DVDit or from DVD2ONE, CopyToDVD will give me an error message like;

BUP/IFO of Video Title set #16 contains error. The resulting DVD may not work.

Even though, the DVD burns 100% and plays on my machine.
Does this mean there is a less likely chance it will play on other machines?
Thus reducing the 80% or so success rate from my Apple DVD-R's?

Usually these types of errors indicate a problem with the IFO/BUP file, and where it points to. These files essentially tell your player where the VOB files are, where they start, and where they stop. If a pointer is wrong, or invalid, then the video may not play. If your lucky, then the pointer may be for some DVD extra that you may never access. This type of error is more common when you extract the main movie file from a DVD without grabbing all the extra's, or menus.

I've had similar reports, including one tiem when I was backing up a dvd-5, so no juggling about was needed. I tried two different things:- I used IfoEdit on the VIDEO_TS.IFO and ran the "get vts sectors" option - this changed several things and rendered the dvd-rw unreadable in my set-top player, although my pc played the disc fine. Then I tried burning in Nero. No errors thrown up, and the disc plays fine.

Go figure.

So, the movie could play a while and then freeze in the middle?

I have been ripping the whole movie, moving the main .vob files, creating IFO's with IFO Edit, using DVD2ONE to re-size the .vob down, then using VOB UPDATE to update the original to the new re-sized .vob. Then burning to COPYtoDVD.

It could. You should use IFO edit last to ensure the IFO's are correct. When you resize, you change the VOBs, so the pointers in the IFO's may not be valid anymore.

[supatrupa]

So I should not be creating IFO's before using DVD2ONE? Is that correct?

Use DVD2ONE, then use the IFO's created by DVD2ONE after the process.

If DVD2ONE creates the IFO's, then yes, let it create them for you, as those will be more accurate than the ones you created with IFOEdit previously. Every time you touch the VOB's with editing/encoding software, it can change them. If the application your using does not create new IFO's to go with the modified VOB's, then you should create them manually to be sure their accurate.
