#1 Burning Software

I am using delphi , and i see your DVDVideoTrackAtOnceFromTree :

Files must be aligned like this:

/VIDEO_TS/VIDEO_TS.IFO
/VIDEO_TS/VIDEO_TS.VOB
/VIDEO_TS/VIDEO_TS.BUP
/VIDEO_TS/VTS_01_0.IFO
/VIDEO_TS/VTS_01_0.VOB
: :
/VIDEO_TS/VTS_01_9.VOB
/VIDEO_TS/VTS_01_0.BUP
: :
/VIDEO_TS/VTS_99_0.BUP

Can i order the files as
VIDEO_TS.IFO
VTS_01_0.IFO
VIDEO_TS.BUP
VTS_01_0.BUP
VTS_01_0.VOB
....................
(Perhaps it is some other orders )


What differences about that?

No, you cannot. Files on DVD-Video disc be created in the order or you'll get a disc unreadable in some of the hardware players.

but some dvds have not VIDEO_TS.VOB or VTS_01_0.VOB file.

Skip the files if they are not used. But do not change the order.

Assuming you have valid files and the correct file order, can you just burn the files to a DVD to make them compatible with DVD players? Or do you need to burn them in a special way?

(e.g. like VCD files that have a special disk layout)

It's StarBurn business and not yours. You just provide files in the correct order and make sure they are valids (VOBs are properly indexed and IFO/BUPs have valid relative offsets - DVD authoring tool must take care of this).

about l__ULONG__GUID

for example:
Inc(l__ULONG__GUID);
l__ULONG__Status =
StarBurn_UDF_FormatTreeItemAsFile(
&g__UDF_TREE_ITEM__File[ 6 ],
( ++l__ULONG__GUID ),
"vts_01_1.vob",
"c:\VOB\vts_01_1.vob",
&l__UDF_TREE_ITEM__Directory[ 2 ]
);

but not all of function need this sentence :Inc(l__ULONG__GUID);
for example:
l__ULONG__Status =
StarBurn_UDF_FormatTreeItemAsFile(
&g__UDF_TREE_ITEM__File[ 8 ],
( ++l__ULONG__GUID ),
"vts_01_3.vob",
"c:\VOB\vts_01_3.vob",
&l__UDF_TREE_ITEM__Directory[ 2 ]
);

Does this have the difference?

And another question :
How to check we need to patch IFOs ?
In your example g__UCHAR__IsIfoPatch has not changed all the time .

Thank you for your help very much .

1) GUID for UDF nodes must be different. In ALL of the nodes.

2) Just change global variable g__UCHAR__IsIfoPatch and relative offsets within image would be changed. Apply this code ONLY if you have problems with hardware DVD players (StarBurn's formatting and DVD authoring tool you use have different relative offsets assuming). Can be get only in experimental way.
