Problems with 10.5.6 & DVDSP

I'm reading a lot of complaints about the compatibility between the two, but I've yet to see a definitive verdict on the issue, or a solution. Personally, I am running DVDSP4 & OS 10.5.6 and have been having lots of problems recently. I was going to chalk them up to issues with my Raid, but given the number of complaints about similar issues, I'm not so sure anymore.
Has Apple acknowledged the issue, or has there been any consensus on the compatibility bewteen DVDSP4 and 10.5.6?

As far as Apple are concerned it isn't an issue to acknowledge. They openly say that you need to upgrade your version of DVDSP... which translates to needing to purchase FCS2 in order to run it on an intel based mac and 10.5.6
I believe \some folk have had limited success getting it all to work by downgrading their version of Quicktime to an earlier state, but the only way to get it running reliably is to upgrade to FCS2, or remain at an earlier version of the OS.

I suspect you are attempting to burn an HD DVD, which will not play on a DVD player...
But if you provide more details such as the settings you are applying in Compressor, then we would be able to provide you more accurate information.
How are you adding the files to Compressor?
In FCP, what are your footage properties (command-9) and sequence settings (command-0)

Please help!!!

Somewhere at either Macworld or here I learned that DVDSP 2, DVDSP 3 and now DVDSP 4 "internally" are major re-writes.
Support for HD among a few other items along with QT 7 which comes with Tiger means sincerely that one set of applications/OS is not going to be stable.
Personally I think of all the issues possible its DVDSP vs QT.
Unless you move to DVDSP v4 the alternative is to wipe the disk and go back to Jaguar (10.2) or perhaps Panther but avoid upgrading QT beyond 6. I advocate wiping the disk because I'n not sure an archive and install to down shift to an earlier version of the OS is possible. If it is I'd still worry about mis-matched files in all sorts of locations.

Problem with bit rate ?

Hi there,
Using FCP7.
After compressing a FCP project with Compressor and burning DVDSP with DVDSP, I realized that scenes containing objects or people in rapid movement where showing jerked images.
The slow motion scenes are fine.
I checked the following
settings for DVDSP burning: VBR two pass;
averageBit rate 4,0,
max rate 7,0
1) the self-contained QT that I started with is not showing this problem.
2) the m2v file obtained from compressor (I use preset setting for high quality compression) does not show this problem when I view it with MPEG streamclip
3) I tried to burn directly the QT file with Toast 10 …get same problem if not worse !.
settings for Toast
automatic re-encoding
average rate 4,0 Mbps
max bit rate 8,0 Mbps
MPEG-2
I guess my problem comes from the bit rate I used ?
I am now confused and I am not sure I understood the impact of the bit rate setting on the quality of the resulting DVD, and I believe that using a high bit rate in DVDSP might result in problems for some clients to play the DVD on their player ?
Could it be something else ?
could someone please give me advice ?
Many thanks in advance
Ivan

I can only think of two possibilities based on the info available:
1. Old DVD player (choking on the bitrate spike)
2. You need to set some compression markers around the scenes while in FCP. This would flag Compressor to pay extra attention to that area. After you output the new clip, I suggest you use the standard High Quality preset (in Compressor) for your program duration e.g., "Highest Quality 90 minute". Don't get creative with the encoding set-up. And ALWAYS used AC-3 audio.

Problem with more than one item in a track

DVDSP 4.0.2 / OSX.4.2 I've built a DVD with several tracks. In each track I've placed several .m2v files, one after another. Finished build plays fine on my Mac and on one of my stand alone DVD players. But on another stand alone (Sony DVP-S360) something very odd happens. DVD begins to play just fine, but whenever it encounters a track with more than one source file, it will play until it gets to the spot in the program where the second source file is in the track and then it hangs and won't do anything. I'm just curious if anyone has any insight into this problem. Is it a DVDSP conflict thing with certain players? Or is this Sony player just not capable of playing a DVD built this way? Thanks.

This page here:
http://www.videohelp.com/dvdplayers.php?DVDnameid=428&Search=Search&
has someone talking about finally getting burned DVDs to work, which suggests they previously had problems. I can't think why the track would not seem like continuous video, as if it had always been that way. Our Sony DVD player at work seems sensitive to higher data rates. What data rate did you use?

Problem with TASCAM website

It is related to FCP. I am using the FW1084 with FCS2. I have some problems with keeping video en audio in sync.
So I looked at the website of tascam and saw the was a new drive fro OS 10.4.10 But I can download it. It direct me to the home page of Tascam.
Even under Windows.
Does anyone out there have this driver?

Hello,
I am back from a holiday and some training.
I treid several things and put my question also in the MXO support group but no aswer yet.
Here is my question/problems And mebay I could ask (trillcat editorial) in a privat email (I tried to click on email but it ask for your email adres.)
y setup is 2 x 23" Apple Cinema MacPro 3 GHz 4 GB Tascam FW 1082 audio/control interface
MXO Software 2.0.0.21 Firmw 20 Serial # TAA4239
I am working with Standaard DV PAL Amamorphic and HDV (1440)1920 1080I FCS 2 (FCP 6.0.1)
OS 10.4.10 (quicktime 7.1.6)
1e Q
Is it normal to set every time the View/Video Playback? It get me ....
Always Command F12 2 times (even when used Option F12)
2e Q
I always must use 2 x Command F12 to get a normal picture on the MXO and Canvas (The video in the Canvas is jumping on the same frame)
3e Q
I just can't get my Audio in sync in Final Cut Pro. (in DVDSP or DVD player it is OK Also output through the Tascam.
Connected accourding to the manual. I have the Audio out from the MacPro in the white jack of the MXO cable and the output to chanel 7 and 8 on my Tascam FW 1082
With no FCP(example iTunes) and in the Preference I set the Audio to Build in Audio Out (which is connected to the MXO audio) it is working but NOT within Final Cut Pro
There is also no Audio when not using the FW 1082 within FCP, only (amplified) speakers are conected to the MXO audio.
Double checked conectors the are OK (offcourse there is audio when not using FCP)
Also tried with easy setuo MXO Pal Anamorhic
Hope to get my MXO work Ok

Problem with Inspector pull-down menus

I have this weird problem with DVD Studio Pro all of a sudden. I'm wondering if a recent update might have broken something, and how I can fix it.
The problem is that certain pull-down menus in the Inspector are not responding anymore. Important ones too, like "set target" and "end jump," Remote Control functions, as well as ones I don't use as often like Shape (button shape?). I click on them and nothing happens, although sometimes the default "not set" text disappears. These menus are in the same place in the Inspector, so this may or may not have something to do with it, I have no idea.
At any rate, I can't make a DVD without these functions, and I usually need to make a DVD once or twice a week. Although it has been two weeks since I last used it.
I am almost positive that nothing has changed with my system since I used it last, besides Apple Software Updates.
Version 2.0.5, OSX Tiger. I know, time to upgrade, but I don't control the budget.

Just the Inspector, i haven't found any other problems.
Quicktime was updated a few days before the problem started. On May 27th I ran the updates for Quicktime 7.4.5, ProKit 4.5, iTunes 7.6.2, and Safari 3.1.1. I noticed the problem with the DVDSP Inspectors the next time I ran the program on May 29.
I understand the ProKit is for a later version so I'm a bit mystified as to why I was offered the update, however I've installed previous ProKit updates without any problems.
A clean install will certainly be my next step. But I have to wait for a lull in real work activity before I can get into that. Luckily I've remembered that I can accomplish a lot of what I needed the inspector for under the Connections tab, so it's a little less urgent now.
I'm usually pretty careful about running updates, and I usually ignore them for a few weeks (or longer) before I run the updates so I can monitor the internet for other people's disasters. But I got lazy this time. Maybe there are not too many DVDSP v2 installations out there. And maybe I need to increase the pressure on my company to update my software!
On that note, this experience is helping my case with convincing them to replace one of the old Avids with a new FCS suite, so it might become a moot point. Will the license allow me to operate DVDSP4 on a different machine or does it have to stay on the main suite, if we go that way? We like to process the output on another box, so the editors can get on with the next project.

Consistant problem with music in menus

Hi For several projects in a row, I have had the same problem with adding music to my menus. The music plays thru for about 30 seconds, then, before repeating the cycle, the first few notes come in for a couple seconds. Why would these first few notes appear between cycles?
Any ideas? Thanks very much, Bob

Thanks for your thoughts, Shawn. This problem is really getting weird, though. Please bear with me: the 30-second aif file that I created for the Menu, was originally taken from a aif part of the movie sound track. I extracted the piece into a sound editing program I use called Peak. In Peak I created a discreet aif file which DOES NOT CONTAIN the notes that constitute the 'blip' which is turning up between cycles of the menu. The notes in the blip don't even exist in the aif file that was dragged onto the menu!! (They are, however, the notes that follow in the original file that the new aif was created from.) How and why would DVDSP find these notes and insist on playing them? This is like Twilight Zone.

Problem with Build/Format tab in Destinations Preferences

Hello-
I recently installed Leopard (10.5.2) and FCS 2 on a clean, erased drive on my Mac Pro. Everything works fine, except for one problem.
I relocated some DVDSP project files to the new drive, and also copied all of the media files for these projects to a new, different external drive. As I opened each project, I had to, as expected, relink the media. Again, this all worked OK.
The problem is, when I want to format (command/f) a DVD, the format dialog window comes up, and the location window is either empty, or shows the location for the wrong project. I can, of course, hit 'choose' and connect it with the correct location, and burn the disc with no problems.
If I then save the project, and reopen it, the same problem will occur. It seems that I will have to type the location in every time I want to burn a disc from each project.
I looked at the destinations preferences, and in the build/format section there is nothing in the location box. I'm not sure what to put here to make it right; I'm sure it can't be something different for each project--I never had to do that before. But I also don't understand how one global setting will fix it so every project opened will point to the correct location.
As I said, everything is working great, but I'd like to reset things as they were before; so that every time I open a project, and choose Format, the correct location for the needed files will just show up.
Thanks in advance for any help anyone can provide.

Well, I've solved it; if I open each project, relink if necessary, and then rebuild the project (selecting REUSE when the 'TS folder already exists' dialog comes up), everything is fine.
It seems like there should be a quicker way to do this, though, or that it shouldn't need to be done at all.

A problem with threads

I am trying to implement some kind of a server listening for requests. The listener part of the app, is a daemon thread that listens for connections and instantiates a handling daemon thread once it gets some. However, my problem is that i must be able to kill the listening thread at the user's will (say via a sto button). I have done this via the Sun's proposed way, by testing a boolean flag in the loop, which is set to false when i wish to kill the thread. The problem with this thing is the following...
Once the thread starts excecuting, it will test the flag, find it true and enter the loop. At some point it will LOCK on the server socket waiting for connection. Unless some client actually connects, it will keep on listening indefinatelly whithought ever bothering to check for the flag again (no matter how many times you set the damn thing to false).
My question is this: Is there any real, non-theoretical, applied way to stop thread in java safely?
Thank you in advance,
Lefty

This was one solution from the socket programming forum, have you tried this??
public Thread MyThread extends Thread{
     boolean active = true;
     public void run(){
          ss.setSoTimeout(90);
          while (active){
               try{
                    serverSocket = ss.accept();
               catch (SocketTimeoutException ste){
               // do nothing
     // interrupt thread
     public void deactivate(){
          active = false;
          // you gotta sleep for a time longer than the
          // accept() timeout to make sure that timeout is finished.
          try{
               sleep(91);
          }catch (InterruptedException ie){
          interrupt();
}

Problem with Threads and a static variable

I have a problem with the code below. I am yet to make sure that I understand the problem. Correct me if I am wrong please.
Code functionality:
A timer calls SetState every second. It sets the state and sets boolean variable "changed" to true. Then notifies a main process thread to check if the state changed to send a message.
The problem as far I understand is:
Assume the timer Thread calls SetState twice before the main process Thread runs. As a result, "changed" is set to true twice. However, since the main process is blocked twice during the two calls to SetState, when it runs it would have the two SetState timer threads blocked on its synchronized body. It will pass the first one, send the message and set "changed" to false since it was true. Now, it will pass the second thread, but here is the problem, "changed" is already set to false. As a result, it won't send the message even though it is supposed to.
Would you please let me know if my understanding is correct? If so, what would you propose to resolve the problem? Should I call wait some other or should I notify in a different way?
Thanks,
B.D.
Code:
private static volatile boolean bChanged = false;
private static Thread objMainProcess;
   protected static void Init(){
        objMainProcess = new Thread() {
            public void run() {
                while( objMainProcess == Thread.currentThread() ) {
                   GetState();
        objMainProcess.setDaemon( true );
        objMainProcess.start();
    public static void initStatusTimer(){
        if(objTimer == null)
             objTimer = new javax.swing.Timer( 1000, new java.awt.event.ActionListener(){
                public void actionPerformed( java.awt.event.ActionEvent evt){
                          SetState();
    private static void SetState(){
        if( objMainProcess == null ) return;
        synchronized( objMainProcess ) {
            bChanged = true;
            try{
                objMainProcess.notify();
            }catch( IllegalMonitorStateException e ) {}
    private static boolean GetState() {
        if( objMainProcess == null ) return false;
        synchronized( objMainProcess ) {
            if( bChanged) {
                SendMessage();
                bChanged = false;
                return true;
            try {
                objMainProcess.wait();
            }catch( InterruptedException e ) {}
            return false;
    }

Thanks DrClap for your reply. Everything you said is right. It is not easy to make them alternate since SetState() could be called from different places where the state could be anything else but a status message. Like a GREETING message for example. It is a handshaking message but not a status message.
Again as you said, There is a reason I can't call sendMessage() inside setState().
The only way I was able to do it is by having a counter of the number of notifies that have been called. Every time notify() is called a counter is incremented. Now instead of just checking if "changed" flag is true, I also check if notify counter is greater than zero. If both true, I send the message. If "changed" flag is false, I check again if the notify counter is greater than zero, I send the message. This way it works, but it is kind of a patch than a good design fix. I am yet to find a good solution.
Thanks,
B.D.

Problem with threads running javaw

Hi,
Having a problem with multi thread programming using client server sockets. The program works find when starting the the application in a console using java muti.java , but when using javaw multi.java the program doesnt die and have to kill it in the task manager. The program doesnt display any of my gui error messages either when the server disconnect the client. all works find in a console. any advice on this as I havent been able to understand why this is happening? any comment would be appreciated.
troy.

troy,
Try and post a minimum code sample of your app which
does not work.
When using javaw, make sure you redirect the standard
error and standard output streams to file.
Graeme.Hi Graeme,
I dont understand what you mean by redirection to file? some of my code below.
The code works fine under a console, code is supposed to exit when the client (the other server )disconnects. the problem is that but the clientworker side of the code still works. which under console it doesnt.

Problem with threads and camera.

Hi everybody!
I've a problem with taking snapshot.
I would like to display a loading screen after it take snapshot ( sometimes i
have to wait few seconds after i took snapshot. Propably photo is being taken in time where i have to wait).
I was trying to use threads but i didn't succeed.
I made this code:
display.setCurrent(perform);
        new Thread(new Runnable(){
            public void run() {
                while((!performing.isShown()) && (backgroundCamera.isShown())){
                    Thread.yield();
                notifyAll();
        }).start();
        new Thread(new Runnable(){
            public void run() {
                try {
                    this.wait();
                } catch(Exception e) {
                    exceptionHandler(e);
                photo = camera.snapshot();
                display.setCurrent(displayPhoto);
        }).start();This code is sometimes showing performing screen but sometimes no.
I don't know why. In my opinion performing.isShown() method isn't working correctly.
Does anyone have some idea how to use threads here?

Hi,
I've finally managed to work this fine.
The code:
       Object o = new Object();
       display.setCurrent(perform);
        new Thread(new Runnable(){
            public void run() {
                while(!performing.isShown()){
                    Thread.yield();
               synchronized(o) {
                  o.notify();
        }).start();
        new Thread(new Runnable(){
            public void run() {
                try {
                    synchronized(o) {
                       o.wait(1);
                } catch(Exception e) {
                    exceptionHandler(e);
                photo = camera.snapshot();
                display.setCurrent(displayPhoto);

Problem with threads hanging

We have a problem where our application stops responding after a few days of usage. Things will for fine for a day or two, and then pretty quickly threads will start getting hung up, usually in places where they are allocating memory
We are running WebLogic 8.1 SP2 on Sun JDK 1.4.2_04 on Solaris 8 using the alternate threading model and the -server hotspot vm. We are running pretty much the same code that we had no problems with under WebLogic 6.1 SP4 and Sun JDK 1.3.1.
A thread dump usually shows that some or all of our execute threads are in the state "waiting for monitor entry" even though they are not currently waiting on any java locks. Here is a sample thread from the thread dump (we have ~120 threads so I don't want to post the full dump).

String.java line 1446 for this jdk allocates a new String object, and all the other threads in this state also are creating new objects or arrays, etc.
We've done a pstack on this process when it's in this state, and the threads that are in the "waiting for monitor entry" that look like they're allocating memory are all waiting on the same lwp_mutex_lock with some allocation method that's calling into the native TwoGenerationCollectorPolicy.mem_allocate_work (see pstack output below for the same thread as in the thread dump above)

Also when it's having this problem, the "VM Thread" is always using a lot of processor time. We did a couple of pstacks today while it was having this problem, and this thread was stuck in the ONMethodSweeper.sweep for over 15 minutes when we finally killed the server.
From the thread dump:

Has anyone ever seen anything like this? I'm trying to figure out if this is caused by something we're doing, or something relating to our environment and jvm options. Any ideas?

Thanks for the reply - I'm testing our app with the +UseConcMarkSweepGC now in our test environment to make sure it doesn't cause any problems there. Unfortunately the only place we've had this problem is on the production server, so it's extra difficult debugging this.
We're using the following memory options:
-ms512m -mx512m -XX:NewSize=128m -XX:PermSize=192m -XX:MaxNewSize=128m -XX:MaxPermSize=192m -XX:SurvivorRatio=8and the following debugging options, as we've also been seeing OutOfMemoryErrors ( see http://forum.java.sun.com/thread.jsp?forum=37&thread=522354&tstart=45&trange=15 )
-verbosegc -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+PrintHeapAtGCBTW, which c++filt version and options are you using? Our Solaris boxes only seem to have the GNU version installed. I was trying to run that on some of the other stack traces and wasn't getting anywhere, and didn't know if because it was GNU version wouldn't work on something compiled with the Sun compiler.
Thanks!

Problem with threads and ProgressMonitor

Dear Friends:
I have a little problem with a thread and a ProgressMonitor. I have a long time process that runs in a thread (the thread is in an separate class). The thread has a ProgressMonitor that works fine and shows the tasks progress.
But I need deactivate the main class(the main class is the user interface) until the thread ends.
I use something like this:
LongTask myTask=new LongTask();
myTask.start();
myTask.join();
Now, the main class waits for the task to end, but the progress monitor don`t works fine: it shows only the dialog but not the progress bar.
What's wrong?

Is the dialog a modal dialog? This can block other UI updates.
In general, you should make sure that it isn't modal, and that your workThread has a fairly low priority so that the UI can do its updating
