>> About "dvdauthor.exe error (_cygtls::handle_exceptions: Exception:
>> STATUS_ACCESS_VIOLATION)".
>>
>> About root cause of this problem.
>>
>> For example I tried to create "DVD VOB" with 296 video files.
>> So my proper "dvd_creater.xml" file contained 296
>> "dvdauthor.titleset.titles.pgc" nodes.
>> "vm_statement" structures will be created at processing of
>> "dvd_creater.xml" file by dvdauthor.exe (dvdauthor.exe -x dvd_creater.xml).
>> For each video file from "dvd_creater.xml" will be created proper
>> "vm_statement" structure.
>> About "vm_statement" structure:
>>
>> struct vm_statement /* for building parse tree */
>>   {
>>     int op;
>>   /* meanings of following fields depend on op */
>>     int i1, i2, i3, i4;
>>     char *s1, *s2, *s3, *s4; /* s1 is label for gotos and label defs; s2,
>> s3, s4 not used */
>>     struct vm_statement *param;
>>     struct vm_statement *next; /* sequence of operations */
>>   };
>>
>> "dvdauthor.exe" module initialize all fields of "vm_statement" structure
>> at processing of "dvdauthor.titleset.titles.pgc" node.
>> So "dvdauthor.exe" put 130 into field "i2" of "vm_statement" structure for
>> the first file.
>> "dvdauthor.exe" put 131 into field "i2" of "vm_statement" structure for
>> the second file.
>> ...
>> "dvdauthor.exe" put 254 into field "i2" of "vm_statement" structure for
>> the file with number 125.
>> "dvdauthor.exe" put 255 into field "i2" of "vm_statement" structure for
>> the file with number 126.
>> "dvdauthor.exe" put 128 (not 256!) into field "i2" of "vm_statement"
>> structure for the file with number 127.
>> "dvdauthor.exe" put 129 (not 257!) into field "i2" of "vm_statement"
>> structure for the file with number 128.
>> ...
>>
>> So in my opinion the procedure of creation/initialization the
>> "vm_statement" structures is not corrected.
>> You can check these values via the "pgc_set_post" (or "pgc_add_button")
>> function (see "vm_parse") in the dvdauthor.c file.
>>
>> Thus, an error will be occurred when the "compilecs"-function (in
>> "dvdcompile.c" file) will be performed on the line 916:
>>
>>
>>    if (cs->i3 && cs->i3 > ws->titles->pgcs[i2 - 128 - 1]->numchapters)
>>      {
>>        fprintf
>>          (
>>            stderr,
>>            "ERR:  Cannot jump to chapter %d of title %d, only %d exist\n",
>>            cs->i3,
>>            i2 - 128,
>>            ws->titles->pgcs[i2 - 128 - 1]->numchapters
>>          );
>>        return 0;
>>      } /*if*/
>>
>> Here "i2" is a "i2" field of our "vm_statement" structure for the
>> processed file.
>> So we have "ws->titles->pgcs[130 - 128 - 1]" when will be processed first
>> file.
>> We have "ws->titles->pgcs[131 - 128 - 1]" when will be processed second
>> file.
>> ...
>> We have "ws->titles->pgcs[254 - 128 - 1]" when will be processed file with
>> number 125.
>> We have "ws->titles->pgcs[255 - 128 - 1]" when will be processed file with
>> number 126.
>> We have "ws->titles->pgcs[128 - 128 - 1]" (i2 for this file is equal to
>> 128!!!) when will be processed file with number 127. - So we have the error.
