"Improper IFO files" -- how to recover?

[laserfan]

I am new to RB-PRO and my first effort resulted in the subject message following the REBUILD process. Oddly, this message does not appear in the log, the latter portion of which looks like this:

Done.

Well, turns out the VIDEO_TS folder I'd picked did not have a proper VIDEO_TS.IFO, so I rebuilt it w/IfoEdit and checked it w/PgcEdit and now it appears OK. So I have two questions:

1. Shouldn't the error message I received from RB-PRO have created a log entry?

2. For some reason adding a proper IFO set to the VIDEO_TS folder now means I have to start over from scratch i.e. pressing REBUILD again yields: "The source path does not match the one used during PREPARE. Rebuild aborted" Is this correct, that I have to start-over from the very beginning, or is there a shortcut available somehow?

There is a variable in the REBUILDER.INF file under the [Status] area that is called ORIGINAL_SIZE. It holds a value that is the sum (in 2048 byte sectors) of the file sizes of the original directory.

You can do a PREPARE using another directory for working, and then copy the resulting value (but not the entire file) into the REBUILDER.INF of the first job. It should then let you REBUILD.

Just in defense of DVD-RB, though -- it's hardly to blame for a source that is missing the VIDEO_TS.IFO file.

You have no argument from me jdobbs about the missing IFO files--I was slapping my forehead about it myself. I thought you might be interested tho that the error it generated was not inserted into the DVD-RB log. I was tempted to ask if the proggie could test for valid IFOs before proceeding; then I thought better of it. No IFOs is certainly not a normal fileset!

Thanks for the suggestion about REBUILDER.INF. I'll give that a try, and I'll be more careful next time in the fileset I choose to rebuild!!!

The other oddity is that my fileset, which was an anamorphic conversion of a letterboxed (4:3) 4.5Gb fileset, is only 4Gb in size, despite that I "scaled it up".

I need to play and read some more but so far I'm impressed.
