personal Studio 1.5 
by PIrgE
This is a great video production app with three protections.
A 30 day timeout, a watermark on all compressed movies exported from the app
and a 30 second limit on upload and downloads to DV cameras.

1. 30 Day Timeout

Load up personalStudio in bdb and enable break on spawn thread
and you will find a section of code like this:
(offsets replaced by **********)

call    0x80****** <AURL::~AURL(void)>
addl    $0x08, %esp
addl    $0xfe, %esp
pushb   $0x01
call    0x80****** <ADemo::TimeoutAlert(bool)>
addl    $0x04, %esp
call    0x80****** <ADemo::Expired(void)>
movb    %al, %al
testb   %al, %al
 //This jump is quit or continue - too easy Adamation
jz      0x80****** <APersonalStudioApp::APersonalStu?+0x00000490>
 //changing to jnz beats the 30 day timeout
 //there are still warnings but I leave that as an exercise for the reader
 //you have to do some work yourself!
pushb   $0x00
pushb   $0x0c
call    0x80****** <ALangFile::str(long, char const >
addl    $0x08, %esp
movl    %eax, %eax
pushl   %eax
call    0x80****** <_init+0x00000378>
addl    $0x04, %esp
pushb   $0x00
call    0x80****** <_init+0x00003318>
addl    $0x04, %esp
nop
leal    (%esi), %esi
pushl   %esi
call    0x80****** <APersonalStudioApp::DisplayCauti>
addl    $0x04, %esp
jmp     0x80****** <APersonalStudioApp::APersonalStu¥+0x000004a5>
 

2. logo on compressed movies
 This is much more interesting.
 Every compressed movie has a logo superimposed so we want to find an image file
somewhere that the app is using.
 
 Take a look at ps.aia in the data directory and you will find a list of
keywords followed by corresponding image files (mostly PNG files).
 The order of the descriptive keywords matches the order of the images.
 Some look interesting such as "watermark" and "embossedlogo" but they are not!
 You could use a hex editor and cut and paste all the images to new files but
there are too many.
 So write yourself a small app to read the file and strip out the image files
and peruse them at your leisure.
 Hey presto there is the superimposed image!
 Find the image position in the ps.aia file by doing a compare on the image file
byte pattern.
 (The one you are looking for is not a png file).
 Open ps.aia in a hex editor and take a look at offsets 00075ffa to 0008a6a5.
 You will find this image is referenced by the string "mediapanel" in ps.aia.
 Now we could create a new image (of nothing or our own watermark) and replace
the logo in ps.aia
 or we could just cut the line
  mediapanel 0 484062 83629
 from the ps.aia file - no more superimposed logo!
 Easy fix but fun to find and a bit of a nice change from jump dont jump!

3. 30 secs on down / up of DV samples
 Unfortunately I don't have a DV camera so I have not worked on this!
 But shit if you have a DV camera you can afford to buy personalStudio.
 
 This text is purely for esoteric purposes - I do not condone stealing software.
 Buy personalStudio if you use it.
