	***************************************
	[1]. Basic use and operation of program
	***************************************
 - Who is this program for?
 
 	  Well basically this program is for use by film projectionists that use
 	a DTS sound processor in their theatre.  Most films today come with some
 	form of digital sound system.  The three most common types are Dolby
 	Digital, SDDS (Sony Dynamic Digital Sound), and DTS (Digital Threatre
 	Systems).  Dolby Digital and SDDS are encoded on the print, but DTS comes
 	on 1 or 2 compact discs.  When the film is played the DTS sound is 
 	syncronized up with the picture by a simple dotted pattern on the film
 	between the dolbySR sound track and picture.  Since different theatres
 	play different trailers, and not all trailers are on one disc we need
 	a program that can seperate the trailers so we can burn them to one 
 	trailer disc.
 	  So this program is for the projectionist that wants to burn a custom
 	made DTS trailer disc.  I worked in a second run theatre where we would
 	play different movies almost every night.  The trailers would also change
 	alot, some old some new.  Even though DTS provides a monthly DTS disc
 	with a bunch of new trailers on it, there would always be some missing.
 	With the DTS Extractor you can keep a back log of old trailers you know
 	that you will play again and mix them in with any trailers you need this
 	week or month.
 	  If you need a custom set of DTS trailers then this program is for you.
 	A disc can hold anywhere from 50 to 70 trailers.
 
 	
  - What it does and does not do.
  
  	  This program simply extracts chunks of data from a DTS disc and 
  	reorganizes them into one large chunk.  It can read both the DTS trailer
  	discs and the regular movie discs with trailers.  Most movies discs
  	contain 2 or 3 trailers that they want you to show with the movie and the
  	DTS trailers, THX trailers etc.  You can extract only the movie trailers
  	you want to keep and build a big disc of trailers.  This program also
  	writes the R14TRLR.TXT file that tells the DTS decoder what trailers
  	are on the disc and where to find them.
  	  This program will not work with DVDs or anything else other than DTS
  	discs for use with film.  It will also not decode the DTS sound or play
  	sound from any DTS source.  It only moves large chunks of information,
  	and rebuilds a custom DTS Trailer disc.
 
  	
 - Why it can be a useful tool.
 
 	  This can be a useful tool if you want to show trailers that do not
 	appear on a single DTS trailer disc and DTS movie disc.  You can also
 	use this program to keep an archive of DTS trailers to be used at a
 	later time.  You can create a disc that contains any combination of DTS
 	trailers from mulitple sources.
  	
  	
 - Basic operation
 
 	  You need a source disc and a destination location.  The source disc can
 	be a DTS trailer disc, DTS movie disc (usually disc A) or a custom made
 	disc or directory on your computer.  The program only copies from source
 	to destination.
 	
 		-Open a source by clicking on 'Open Disc'
 		-Find the R14.TXT or R14TRLR.TXT file
 			Note: R14.TXT are usually on movie discs and R14TRLR.TXT
 			are on DTS trailer discs
 		-A list of trailers should appear in the Source list box
 			Note: Trailer names are 8 or fewer characters
 		-Either open a new disc 'Start New Disc' and choose a location
 			or continue a disc 'Continue Disc' and find R14TRLR.TXT
 			Note: You will need up to 700MB of free space
 		-If you chose 'Continue Disc' a list of all trailers added
 			to that disc should be in the Destination list box.  If
 			you chose 'Start New Disc' then the list box is blank
 		-Now select one or more (hold CTRL for muliple) trailers and hit
 			the 'Add -->' button
 		-A Dialog box should popup listing the trailers that it copies
 		-Open more sources if you want to add more trailers
 		-Close discs when finished
 	
 	 	  
 	Note:  When you have finished adding the last trailer and are ready to burn
 	the cd you need to always add sil2sec to the end, it is the sound that plays
 	between	trailers when there is no sound so that it does not drop the DTS
 	stream and return to dolby.  Also you should add dts and dtssonic to all
 	your discs since these are the cool dts sound trailers you usually see before
 	the feature.

	[2]. Burning a custom CD
	************************

 - Finishing steps
 
 	  So you have all the trailers you need in one big chunk and you want to
 	burn it to a CD.  Here is what you need to know to finish the process.
 	If you look in the directory where you put all the trailers you should see
 	two files, R14TRLR.TXT and R14T5.AUD.  R14TRLR.TXT can be read using a basic
 	text editor like notepad or wordpad.  It is just a list of trailers, lenghts,
 	offsets and other numbers.  The other file R14T5.AUD is the big one with the
 	digital dts information.  Obviously the size of these files can not be larger
 	than 650MBs for regular blank CDs, you can also use the 700MB ones if you
 	want.  Now the CD will need to be in the form below:
 	
 	[Root]/-|--DTS.exe
 		--|-/DTS
 		  -R14TRLR.TXT
 		  -R14T5.AUD
 		   
 	Take a look at any DTS disc in your computer to better understand what I mean.
 	In the root directory there is 1 file DTS.exe (can be found on any DTS disc)
 	and one directory called DTS.  In the DTS directory are the two files R14TRLR.TXT
 	and R14T5.AUD.  Thats it, just copy the DTS.exe from any DTS disc and make sure
 	that you name the directory that contains the R14TRLR.TXT and R14T5.AUD files DTS.
 	Burn it to a black cd and you should be ready to go.

	[3]. Trouble shooting
	*********************

 - Version 1.2 Changes
	
	Update to read new DTS trailer infomation files that end with spaces not just
	carraige return and line feed.

 - Version 1.1 Changes
	
	Basically the only change so far is to account for non-standard lengths in the
	headers for the DTS text file.  

	
 - What to do if something does not work
 	
 	  Burned cd does not work at all!
 	  	- DTS decoder just spits the cd out.
 	  	
 	  	  	Something is wrong with the way the disc was burned.
 	  	  	Do not used re-writable disc, I haven't got them to work.
 	  	  	Make sure the directory structure is correct.
 	  	  	
 	  	- Some trailers play DTS and some do not.
 	  	
 	  		Ok this is a real problem.  Some trailers come in different
 	  		versions.  Like some films have teasers and trailer 1,2,3...
 	  		You have to make sure that you have the correct version of
 	  		the trailer to match the correct version of the sound.
 	  		Harry Potter and the Chamber of Secrets have at least 2 
 	  		different trailers trl #1 and trl #2.  They are called
 	  		hpchbtr2 and hpot2tr1 on the cd.  If you only copied one
 	  		and are playing the other the DTS decoder will not be able
 	  		to find the sound and it will drop the DTS and return to 
 	  		dolby.  Make sure that you read the label on the trailer
 	  		and make a note of it so that you can copy the right sound
 	  		file for the right trailer.  I have seen some films with 
 	  		8 different trailers.
 	  		By the way, it does not matter if a trailer is scope or flat
 	  		as long as the trailer number is the same.  The Blade 2
 	  		trailer came in scope and flat but both used the same trailer
 	  		sound file on the DTS disc.
 	  		
 	  	- Anything else
