NTSC <-> PAL VOB conversion?

All,
Now that I've figured out how to back up my DVDs, using libdvdread,
cdrecord and dvdbackup, I'm curious to know if anyone's managed to
figure out a way to convert the VOBs to a different video format.
The dvdbackup program I use creates a directory structure on disk
that one can mess with. Any ideas?

/* Usage:
To gather info about the dvd:
dvdbackup -i /dev/dvd -I
Gerneral backup information:
If your backup directory is /my/dvd/backup/dir/
specified with the "-o" flag. Then dvdbackup
will create a DVD-Video structure under
/my/dvd/backup/dir/TITLE_NAME/VIDEO_TS.
Since the title is "uniq" you can use the same dir
for all your DVD backups. If it happens to have a
generic title dvdbackup will exit with a return value
of 2. And you will need to specify a title name with
the -n switch.
dvdbackup will always mimic the original DVD-Video
structure. Hence if you e.g. use the -M (mirror) you
will get an exact duplicate of the original. This
means that every file will be have the same size as
the original one. Like wise goes also for the -F
and the -T switch.
However the -t and (-t -s/-e) switch is a bit
different the titles sectors will be written to the
original file but not at the same offset as the
original one since they may be gaps in the cell
structure that we don't fill.
To backup the whole DVD
dvdbackup -M -i/dev/dvd -o/my/dvd/backup/dir/
This action creates a valid DVD-Video structure
that can be burned to a DVD-/+R(W) with help of
mkisofs version 1.11a27 or later
To backup the main feature of the DVD:
dvdbackup -F -i/dev/dvd -o/my/dvd/backup/dir/
This action creates a valid DVD-Video structure
of the feature title set
dvdbackup defaults to get the 16:9 version of the
main feature if a 4:3 is also present on the DVD.
To get the 4:3 version use -a 0.
dvdbackup makes it best to make a inteligent guess
what is the main feature of the DVD - in case it fails
please send a bug report.
To backup a title set
dvdbackup -T 2 -i/dev/dvd -o/my/dvd/backup/dir/
where "-T 2" specifies that you want to backup
title set 2 i.e. all VTS_02_X.XXX files.
This action creates a valid DVD-Video structure
of the specified title set
To backup a title:
dvdbackup -t 1 -i/dev/dvd -o/my/dvd/backup/dir
This action backups all cells that forms the
specified title. Note that there can be sector
gaps in between one cell and an other. dvdbackup
will backup all sectors that belongs to the title
but will skip sectors that aren't a part of the title.
To backup a specific chapter or chapters from a title:
dvdbackup -t 1 -s 20 -e 25 -i/dev/dvd -o/my/dvd/backup/dir
This action will backup chapter 20 to 25 in title 1, as with
the backup of a title there can be sector gaps between one chapter
(cell) and on other.dvdbackup will backup all sectors that belongs
to the title 1 chapter 20 to 25 but will skip sectors that aren't
a part of the title 1 chapter 20 to 25.
To backup a single chapter e.g. chapter 20 do -s 20 -e 20
To backup from chapter 20 to the end chapter use only -s 20
To backup to chapter 20 from the first chapter use only -e 20
You can skip the -t switch and let the program guess the title although
it's not recomened.
If you specify a chapter that his higher than the last chapter of the title
dvdbackup will turncate to the highest chapter of the title.
Return values:
0 on success
1 on usage error
2 on title name error
-1 on failur
Todo - i.e. what's on the agenda.
Make the main feature guessing algoritm better. Not that it doesn't do
it's job, but it's implementation it's that great. I would also like
to preserve more information about the main feature since that would
let me preform better implementations in other functions that depends
on the titles_info_t and title_set_info_t strcutures.
Make it possible to extract cells in a title not just chapters (very
easy so it will definitly be in the next version).
Make a split mirror (-S) option that divides a DVD-9 to two valid DVD-5
video structures. This is not a trivial hack and it's my main goal
the next month or so. It involves writing ifoedit and vobedit
libraries in order to be able to manipulate both the IFO structures
and the VOB files. Out of this will most probably also come tscreate
and vtscreate which will enable you to make a very simple DVD-Video
from MPEG-1/2 source.

the title set with most chapters is the main film. Number of angles is

and title sets. Tradtionaly the main film has many audio streams
since it's supposed be synconised e.g. a English film syncronised/dubbed
in German. We are also keeping track of sub titles since it's also indication
of the main film*/

The biggest one is usally the main film*/

again tradtionaly title one is belonging to the main film*/

I sketch in the comments - beside it will help you understand the code*/
/* Okay lets see if the biggest one has most chapters, it also has more subtitles
and audio tracks than the second one and it's title one.
Done it must be the main film
Hmm the biggest one doesn't have the most chapters?
See if the second one has the same amount of chapters and is the biggest one
If so we probably have a 4:3 and 16:9 versions of film on the same disk
Now we fetch the 16:9 by default unless the forced to do 4:3
First check which one is which.
If the 16:9 is the biggest one and has the same or more subtile, audio streams
then we are happy unless we are in force 4:3 mode :(
The same goes in reverse if we are in force 4:3 mode
Hmm, in force 4:3 mode - now we check how much smaller than the biggest one it is
(or the reverse if we are in 16:9 mode)
Generally a reverse division should render in 1 and with a small modulo - like wise
a normal modulo should give us a high modulo
If we get more than one it's of cource a fake however if we get just one we still need to check
if we subtract the smaller one from the bigger one we should end up with a small number - hence we
need to multiply it more than 4 times to get it bigger than the biggest one. Now we know that the
two biggest once are really big and possibly carry the same film in differnet formats.
We will now return the prefered one either 16:9 or 4:3 but we will first check that the one
we return at lest has two or more audio tracks. We don't want it if the other one has a lot
more sound (we may end up with a film that only has 2ch Dolby Digital so we want to check for
6ch DTS or Dolby Digital. If the prefered one doesn't have those features but the other once has
we will return the other one.
