Ifoedit / Ifoupdate - plays on HD but Nero and Prassi reject

[sidders]

I have followed carefully the guide for CCE / IFOEdit, but I am having problems.
I have used Scenarist and Maestro, the film plays OK on the HD but Prassi rejects it and I get a file allocation error in Nero, If I continue with the burn, it doesn't play in my standalone.

I use IFOUpdate to change the ifo, then copy all the other vobs back again. It it because there are now a smaller number of main menu VOBs? Like I say, menu's , extras etc work fine on HD.

Can anyone help?

I think you may have it backwards. You should first copy the files into the original directory -- then run IFOUpdate. If not, the sector pointers will not be corrected properly... that's what takes care of the fact that your VTS size is smaller.

The other option is to use IFOEDIT or IFOUpdates "Get VTS Sectors" or "Correct Sectors" options after the fact.

Trying to burn a disc that hasn't had sectors corrected after shrinking down from DVD-9 to DVD-5 will almost certainly cause rejection in Prassi or failure after burning with other software.

Sorry - I didn't make it clear - I do copy the newly authored files to th original directory, replacing the old main movie VOBs. I correct VTS sectors when i do the IFOUpdate thing.

Okay. But in my experience every time I've seen a DVD that worked on my hard drive (with PowerDVD) but failed when it was burned -- it has been associated with "Correct VTS Sectors"

Since you can't normally control where something is written on your hard drive, the playback software lines up the files internally, opens them individually, and simulates sector reads. On a standalone unit, or when playing on your DVD-ROM player, the actually physical sector offsets are used, usually relative to some offset point. When they aren't correct -- it chokes.

Since that is the only real difference it normally has to either that -- or a bad burn...
