Ive done the math, still need help with calc timecodes 00:00

Hi,
Can anyone guide me in the right direction for calculating
timecodes for vcds2.0 for entry in a XML description.

NOTE 1. I'm using UleadDVDfactory to create chapters for a VCD2.0 title
and because of Uleads search for Scene Location Frame option, it is
very accurate for setting "chapter points".

NOTE 2. I then want to use these time code chapter points in my various XML
files. why XML ? because ive templates for 9 chapters on a single menu, motion
mpeg menus and just find more possiblites for templates then what UleadDVDfactory
preset tmeplates offer. (eg. 6 chapters max. for 1 page)


Anyways, these are the scene selections i authored for a 9 chapter VCD2.0 from DVDfactory...
(please note these "entry points" are APS compliant and hit the "I" frame in gop spot on.)

chapter 1 00:00:00:00
chapter 2 00:03:27:12
chapter 3 00:11:04:08
chapter 4 00:18:15:04
chapter 5 00:25:08:14
chapter 6 00:31:49:06
chapter 7 00:35:06:15
chapter 8 00:40:04:22
chapter 9 00:45:29:20


ok then, this is how i converted the time codes for input in the XML stream---->




<entry id="entry-002">207.12</entry>
<entry id="entry-003">664.08</entry>
<entry id="entry-004">1095.04</entry>
<entry id="entry-005">1508.14</entry>
<entry id="entry-006">1909.06</entry>
<entry id="entry-007">2106.15</entry>
<entry id="entry-008">2404.22</entry>
<entry id="entry-009">2729.20</entry>



...and this is how UleadDVDfactory converted the time codes (i burnt the vcd
made a *.*bin file and used VCDXRIP to generate this XML description)




<entry id="entry-002">207.480000</entry>
<entry id="entry-003">664.320000</entry>
<entry id="entry-004">1095.160000</entry>
<entry id="entry-005">1508.560000</entry>
<entry id="entry-006">1909.240000</entry>
<entry id="entry-007">2106.600000</entry>
<entry id="entry-008">2404.880000</entry>
<entry id="entry-009">2729.800000</entry>


So, in conclusion i deduced the number preceding the decimal point is the correct
seconds timcode... but how is numeral value "after" the decimal point calculated ?

00:03:27:12
hh:mms:ff
I I
I I
I I
I I
I I
I IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII
I I
I I
3 minutes X 60 seconds = 180 seconds + 27 seconds = TOTAL 207 seconds

the last :ff how do i calculate ?

draven: From the way the numbers work out I assume this is encoded in PAL at 25 fps because the math works out to be
ff/25=number after decimal point
