SCC file quirks when viewed in Apple DVD Player

Greetings all,
I have a bunch of DVDs with closed captioning that I am implementing by importing scc files. Everything works fine and looks gereat on set top players and even most software players running Windows. However, on the Mac running Apple DVD Player 4.0 or higher (OS X), there are a bunch of quirks during CC playback. Among them are:
1. First and second lines of CC swap places (second line appears above first line)
2. First line doesn't appear at all, but second line does.
3. First line appear at top of screen while second line appears at the bottom.
These issues are showing up on multiple projects using burnt discs (not builds or in simulator). Again, the CC look fine on set top machines and on PCs running Windows.
Is this an issue with DVDSP? With Apple DVD Player? Or with the SCC files I'm working with? The files were delivered from the caption house and I have no way of opening them to look at the formatting.
Thanks in advance for any help.
Best,
Todd Nocera

Hi Todd,
I haven't seen this abberation but I am in PAL land. It doesn't surprise me though. DVD Player has numerous issues with adhering to the spec. If you are happy with the playback on all but a Mac I would proceed. If you are really worried when you go to replication you can have this looked at by the engineers ie through MEI or their in house testing systems.
Your caption supplier will also be able to examine the integrity of your VIDEO_TS build.
For future reference most captioning houses can supply you with the encoded mpeg rather than relying on DVDSP.
Good Luck

Problems playing DVD in Apple DVD player

Hi guys. I am having some trouble with a DL DVD I burned in DVD SP 4.1.0. The DVD plays correctly everywhere (set tops and computers) except when using the Apple DVD player 4.0 (I think that's the version that came with OS 10.3.9.). I have a newer version of the player on my system and everything works fine but when I send the disk out for testing, it comes back with a ton of errors when played on an older version of the Apple DVD player - buttons not working properly, video tracks not followng the end jump, menus not linking, etc.
Is this a known issue between DVD SP 4.1 and Apple DVD player 4.0 (or DL disks and Apple DVD 4.0)? What should I do about this? I've burned DL disks in DVD SP 2.0 before without any problems. I just recently upgraded to 4.1 and now am having this issue. If I maybe use Roxio to burn the disk would that help? Anyone have any experience with this issue? Thanks?

If I maybe use Roxio to burn the disk would that help?
I personally think it would.
I always use Toast to burn discs
Past experience has shown that when DVDSP has burned the discs they often had errors, the same projects burned using Toast produced faultless results
I now author in DVDSP, building the VIDEO_TS folders to the hard drive, then burn these to disc using Toast.

Inferior quality when viewing a built DVD in on a computer

I've seen a few postings with similar problems but have yet to find any good solutions. I'm creating a DVD and many of my client's clients will be viewing it on computers instead of NTSC monitors.
No matter how high I set the encoding bitrate in DVDSP (they say to never go above 8Mpbs - and that's pushing it), the menu screens and text in particular look really crappy when viewed on a computer. I've tried having the text be part of the background instead of a separate graphic, as well as using the text feature in DVDSP. I've run NTSC color filters in Photoshop and the font I'm using is thick and sans serif; but no matter what I do, once the DVD project is built and viewed via the Apple DVD Player (or any player on the computer) it just looks too compressed and not good. I've saved my menu graphics from Photoshop in a variety of formats (ended up using TIFFs), and tried a variety of text colors.
Unchecking "Deinterlace" in the Apple DVD Player makes it look a little better when viewing, but there's no way to automatically force a users computer to change this default setting, so no real help there.
Even further, if I export one of the files as an m2v in a separate app like QuickTime or Compressor and view it in QuickTime, it doesn't look nearly as bad as after DVDSP builds the project and does its encoding. I've tried 2 pass VBR, 1 pass, etc. Pretty much every possible setting/preference.
There has to be some way to improve the quality of still menus and text so that it looks decent on a computer monitor as well as on a TV when building a project with DVDSP.
Does anyone have any tips or suggestions?
Thanks!

Thanks for following up Chris - I apologize for any lack of detail in my posting.
Yes, I am mostly talking about quality concerns with menus though this is not specified in the title of the post. I understand that there is always loss in general quality when compressing as mpeg2, but to be more specific than before, text quality in the menus looks too artifacted around the edges. My client has described it as being "not sharp" and/or blurry.
I have used the proper resolution for the stills in Photoshop, and have experimented with using both 720x480 and 720x534. The problem is not with highlights, as the selected/activated states are separate elements from the text itself (rectangles that appear below the text).
In terms of viewing, I'm aware that scaling up to full screen will degrade the quality. It certainly looks better when viewed at normal size but it would still be nice to be able to control the compression on the still menus so that everything didn't appear as artifacted.
The eye is more forgiving when watching video because of the movement, but on the still menus the loss of quality is much more apparent.
Perhaps (as suggested) encoding the m2vs in Compressor first and then bringing them into DVDSP would yield better results than having the built-in encoder do the job (though my understanding was that it is essentially the same encoder).
My reference to viewing the m2vs in QuickTime was simply to point out the difference in apparent quality when viewing the m2v before DVDSP builds the project - when looking at the m2v in QuickTime the quality appears much better than when you view the DVD project in the Apple DVD Player after the project is built (even though DVDSP is using the same m2v). My concern/question with that issue is just to wonder if DVDSP does some kind of extra compression/encoding on an m2v when it builds the project, and if this can be controlled.
Thanks again for your comments and suggestions.

Although all photos in my libraries are rotated to the correct orientation, random pictures still show up in the wrong position when viewed on Apple TV. Any suggestions?

Thanks for your comments
Several of our iPhone users in the UK reported the problem this morning, and as the Apple fan in the office I've got the job of resolving the issue
The original Excel was an old .xls file, but I have saved it as a .xlsx and the problem still appears
I haven't spoken with our developer yet, but I assume he has created the Excel file using some programming tools rather that directly using Excel
In the meantime I have created a simply spreadsheet with 8 cells contain values
In the first 4 cells, I have formatted them using Currency, and have used the currencies USD, DEM, GBP and CHF
In the remaining cells I have formatted them using the Accounting option, using the same currencies
When I review the spreadsheet on the iPhone (or iPad), the first 4 remain the same yet the last four all show the £ symbol
I have now changed the Region Format of the iPhone to United States, and when viewing on the iPhone the bottom 4 values are now all showing the $ sign!
If I had created the spreadsheet I would have put the Currency code in a seperate cell and purely used a numeric format for the number, and there would be no issue. That might be the only solution
Yes, the Director has the full MS Excel app on his Windows 8 device, but I can't expect all of our clients to go and do the same, in business many of them will have the iPhone
We may have to change the way we produce the report because of Apple's failings here, and it's not the first time that we have had to change something because Apple devices can't display them properly
In business, submitting a potential job contract only for the recipient to get the wrong idea of the costs is a major concern

Audio Glitch in Apple DVD player when at the end of a story

Hi Could anyone shine a light on why when I build and open up my dvd project in Apple dvd player there is an audio glitch. But on the original mpeg there is no audio glitch there. I have chapter markered my project in fcp. I have ten storys and one chapter in each story.
when played on a dvd player the glitches are not heard
Any help on this matter would be great.
sam

in Apple dvd player there is an audio glitch. But on the original mpeg there is no audio glitch there.
when played on a dvd player the glitches are not heard
Have you played the DVD with more than one player without hearing glitches? What, exactly is the glitch? A click? In any case what you report suggests that there is a problem with Apple's DVD Player.
Do you hear the glitch when you play the DVD (the physical disk) with Apple's DVD Player?
I seem to be having a similar problem, but I haven't burned a disk and used a DVD player to play it. See this thread: http://discussions.apple.com/thread.jspa?threadID=1863240&tstart=0
DVDSP shows my soundtrack file to be longer than what it actually is. Is that the case in your situation?

Having trouble with apple DVD player playing Mpeg-2 file

I have this error on my ibook when i try to play an mpeg-2 file recently created through HD - Export/Using quicktime conversion.
The error from Apple DVD player is Dvd Player encountered a system error. could not detect a valid media file. [-70001]
Is there something Iam doing to this when i cut it? I have the same problem on both my laptop exppress harddrive, desktop express version 2.
Is tere a different way I should do this?
Thanks

Hello Richard,
That error code suggests that the region code has been changed 5 times. You can only change the region 5 times in iDVD.
Have a look in here
for some alternate players. There are some really good ones.
I hope that helps some.

MPEG 2 files jittery in QuickTime player & Apple DVD Player

I'm not sure if this is a QuickTime issue or not, but I am having trouble playing back MPEG 2 files in the QuickTime Player, and also in the Apple DVD Player.
During pan shots there is a noticeable jitter which is not there in the original footage. I have made the MPEG 2 files in Compressor, and also in DVDSP, and used a variety of settings to no avail. All the files I've tried play back fine in VLC, and also play back fine when burnt to DVD and played on my television.
Any suggestions?

Well, that's the odd thing. It looks fine on the CRT TV. And in VLC Player it looks ok too. But in QuickTime and DVD Player it looks shocking. I took the DVD to work and played it on my PC there and it looks pretty awful there too. I take your point about being overly sensitive, but I showed it to my partner who is not the perfectionist nerd that I am, and he mentioned it without me even saying anything. Funny thing is, it seems to only be on the MPEG 2 files. I output last night as an MPEG 4 (figuring I'd have to put the footage on the web instead of on DVD) and there was no jerky problem with that file at all.

Apple DVD Player freezing PowerBook when power adapter unplugged

I've got a 15" 1.5GHz G4 PowerBook (previous generation, bought in August 2005) with 1Gb RAM and a Combo drive, running OSX 10.4.2 (not 10.4.3)
When I play DVD movies through Apple's DVD player, and then eject the disc (by clicking the eject button in the DVD player window), everything is normal, until I unplug the power adapter (while the computer is running, but without the DVD in the drive). Then, everything freezes - the pointer locks up, the keyboard locks up, everything. The only way to get out of this is to hold the power button down.
What could be causing this? Is it because I'm ejecting the disc while it's essentially still playing (I keep on forgetting to press the "Stop" button)?
It's also only started doing this since I installed drivers for my new Epson Stylus D88 printer - could this be a problem?
I've repaired permissions, and that seems to have done nothing.
Note: Apple DVD Player is not running when I unplug the power adapter, nor is the DVD in the drive.
Any ideas?
Thanks for the help

I've found out that it's not actually a total freeze, it's a 10 second hang and I'm impatient!!
But, during the hang, it appears as if everything is frozen.
I'll contact Epson - I downloaded an update to the printer driver, but that doens't seem to have done anything. I can't uninstall the printer driver, as I'm currently at university, and I don't have the installer CD with me for the printer.

Clock freezes after using Apple DVD Player

I am having a small and annoying issue with the Apple DVD Player (v 4.6.5). This just started happening recently. Everytime I run a DVD (or video TS file, etc) on the software player-it performs as usual. After quitting the application and choosing to eject the disc, I notice there is a longer lag from when I first used the computer, then the little colored wheel of death spins, and eventually Apple DVD Player closes.
The problem, however, is after the application is closed out, my time freezes in the status bar in the upper right hand corner of the screen. (As I write this it says 1:16 and the time in the apple "date and time" preferences panel of OSX says it's 2:14-which is the real time) If I drag the cursor up to the time status bar in the upper right hand corner, it turns into the spinning color wheel, and back again once dragged out.
Once the computer restarts, the time in the upper right goes back to normal with no spinning wheel (until I open Apple DVD Player and quit out of it again). I know this is not an earth-shattering issue, but it is fairly annoying and abnormal. If anyone has suggestions, please help.

It sounds like you found your answer but I also wanted to mention that this is a known BUG when using DVD Player and the Digital Optical Out of a G5. If you look at activity monitor when the Clock is dead and you get the Beach Ball the SystemUIServer will be listed as not responding. If you Force quit this process everything should start working again. As long as the LoginWindow Process is running the SystemUIServer will restart when needed after the force quit.
HOWEVER, The other part of this bug with Digital Optical Out is that sometimes the LoginWindow Process will also stop responding. In this case a Log-Out is the only way to correct the problem. The third part of this bug is sometimes the Finder also stops responding but a Relaunch will fix that.
As I said it sounds like you found your problem but I wanted to post this incase others out there using the Digital Optical Out read this and don't correct their problem.
Also, If you were using the "DOO" by deleting the .plist will set the DVD player back to SYSTEM falsely making one think the problem is fixed.
Last I know this is a known bug because I submitted it as a bug to Apple and received an e-mail stating they know of this problem already.

Scripts works in Simulator and Apple DVD player but not on TV

I have a basic project with two different tracks.
The first one is video and audio. Plays "as is".
The second has video, two audio and one subtitle. Depending on which button, the second Track should be played with different audio and with/without subtitles.
(I use GPRM 1 to set the subs stream, GPRM 2 for the audio and GPRM 3 for menu button navigation).
On the second Track I have a pre-script that sets the streams depending on the value of GPRM 1 and 2.
Works fine in Simulator and in Apple DVD player, but not on the stand-alone player.
Any idea what might be the issue here?
in short:
Button 1: Play Track 1 "as is" (audio 1, no subs)
Button 2: Play Track 2, audio 1, subs on
Button 3: Play Track 2, audio 2, subs off
Button 4: Play Track 2, "as is" (audio 1, subs off)
Menu button and End Jump should go to the corresponding menu button.
Many thanks for your help.

It is part personal preference, part artistic, part what makes the user experience the best so there may not be one "right" answer and I have often made menus one way than changed them when viewing the DVD for something that seemed to work better.
Looking at you description I started playing with some ideas in my head and started typing them, then changed what I was writing
It sounds like you want chapter selections for both track 1 and track 2? If so it may make sense to have the initial menu have Track 1 and Track 2 buttons which then link to sub menus where there is "Play All," selections for each section of each movie and one last button for the preferences.
Alternatively you could also place the preferences selection button on the main menu, though since Track 1 does not sound like it really has preferences you need to make sure that users do not become confused and think they have turned something on/off and are not seeing these options when they thought they selected them when they play back Track 1.
Also with 6 to 8 chapter markers you may be getting close to the point where scripting could make it easier if your selections are just to play the sections - in other words for track 2 four stories take care of the combinations Audio 1/Sub Off, Audio 1 Subs On, Audio 2 Subs Off, Audio 2 Sub On. If the chapter selection starts the track a scene then plays through you can target chapter markers in the story so 4 stories takes care of it. If you are just playing sections you would need 4 x 6 or 8 chapters - 24 or 32 stories roughly. But it is actually fairly quick to do - just set up the intial Play All with all subtitles and audio selections unchecked except for "1" then copy from there. Probably should take under 10-15 minutes or so
Put a real quick thing together for a quick view of the tracks. I can flesh it out more if you like.

The main menu will be the title menu, then the sub-menus (including the set up menus) can be placed in the same VTS as the applicable tracks which can help a bit with DVD performance speed. Since there is 6 to 8 chapter markers on a track each of the main sub-menus would have 8-10 buttons which can work in the design.

Missing lower 25% of the screen ONLY in Apple DVD player

Hi everybody,
I just made a showreel DVD (1 menu, 1 video track) in DVD SP 3.02. It plays back correctly on all dvd players (stand alone, PC) except Apple DVD Player: it strechtes the menu and the video vertically so it's missing the lower 25% of the screen. When I press 'pause' while the video is playing, and then 'play' again, it jumps to the correct aspect ratio. But after ejecting and inserting it again, the same problem appears. I really want to solve this problem, because a lot of my clients use their apple laptop to watch the dvd. Is there a setting I'm missing?
Here are the specs:
- Movie in FCP (DV PAL, 720x576)
- Export using Compressor, 60 minutes high quality encode
- To DVD studio Pro 3.02, PAL, 4:3
Thanx,
Ward, Netherlands

Thanks for your reply, but the problem hasn't been solved yet. There are no assets in my menu (only a small button with text, in the center of the screen), and my video is already 720x576.
I do get some warnings when I build/format my DVD. After it says 'compile completed succesfully' and before it starts formatting, it says this:
Warning: The directory ‘/Users/ward/Desktop/test2/VIDEO_TS/Render Data’ will not be included in the final disc.
Warning: The file ‘VOB_DATA.LAY’ found in the VIDEO_TS folder will not be included in the final disc.
Warning: The file ‘WARD.layout’ found in the VIDEO_TS folder will not be included in the final disc.
Could this have anything to do with it?

Screensaver in Apple DVD Player - what does this mean?

Hello,
I am building a dvd based kiosk using a MacPro and Apple DVD player running to a large plasma monitor. The setup works great except for the fact that when the kiosk is not being used, the menu screen will cause a burn-in on the monitor (this monitor does not offer display tracking, anti-burn technology). It appears that in DVD Player version 4.6.5., Apple has taken this into account and offered a preference under "Full Screen" to "Allow Screensaver on DVD menu in kiosk mode" - this sounds like what I need. However when I select this option, and kiosk mode, the screensaver never starts. I have played around with all of the settings in the DVD player and screensaver, but nothing works. - thanks you in advance for any suggestions!!!!
MacPro 2ghz Mac OS X (10.4)

I think I just answered my own question!
I can get around using a screensaver if I set DVD Studio Pro to timeout the main menu to a looping "screensaver type" video that I can create. This would allow the viewer to watch any video on the DVD, which would end by going to the main menu, which would then stay on the screen for two minutes, and then start the "screen saver video", I can then put a clear screen size button over the entire screen, so that the user can press enter to sent them back to the main menu. This will actually work a lot better than the Apple screensavers anyway..

First Play "Not Permitted" on Apple DVD player

I have some duplicated DVD-Rs of a project, and the client ha reported a disutrbing error. I've been told that on several different Macs running OS 10.2 - 10.4, not only does the disc not auto launch DVD player and not auto-play the first play menu, but when the user presses play on the floating control, they get a "Not Permitted" message. The user reported that they were able to choose "open Video_TS" and navigate to the VIDEO_TS folder on the disc, at which point they were able to get the disc to play.
The disc include a significant amount of content on the ROM sector of the disc, including an autorun and an .exe file for windows users. However, I can't see how the presence of these ROM files could interfere with the operation of DVD Player and the VIDEO_TS folder on the disc.
Furthermore, the duplication master for this disc has been formatted directly from DVD studio as a standrd DVD volume - no Toast burn, hybrid volume formatting, anything like that.
Upon inspection I discovered that my authoring assistant had specified a pre-script on the first play menu. I try never to use pre-scripts for anything, as I have found the way DVD studio handles them to be unreliable. However, I suspect this pre-script on the first play menu as the culprit in this problematic behavior, and have removed it.
The problem consists in that I did not experience this problem with any of the DVD-R checkdiscs I burned from DVD studio, unti the discs were duplicated. We'll be doing a full-scale replication run as the next step. Since I am not able to reproduce this problem on discs I burn here, I'd like find a way to know I have fixed the problem.
My question is, has anyone else ever encountered issues with their first-play menu throwing up this "not permitted" condition in Apple DVD Player? Has anyone ever found a connection between this issue and pre-scripts, or between this issue and any ROM files?
I suspect that DVD studio's pre-scripts are "simulated" or translated through the abstratction layer of DVD studio in a way that allows them to be outside the DVD spec, or perhaps there are other ways DVD studio might be using the pre-command on a menu, such as when you specify a button selection for a menu, that use the menu pre-command, and override the pre-script you might have spcified for the menu.

I've seen it on replicated masters when a dvd-r master was used and not all regions were selected as ok to play. DSP doesn't 'check' region 7 by default... its best to use a region all project and .img files, not VIDEO_TS builds to the HD.
How were the discs duplicated though? That is probably the cause of the problem, not the pre-Script. Maybe a 'Data' disc was burnt and not a DVD-Video type option...

Buttons don't navigate properly in Apple DVD Player!

Hello there,
This is extraordinarily frustrating! Can somebody please help ASAP?
We're running DVD Studio Pro 4.0.2 on Mac OS X 10.3.9, and we just finished authoring a DVD with a layered menu created from a Photoshop document.
When we put the DVD into a normal DVD player connected to our television, the remote control works as expected to navigate through our buttons. When we press right, it goes to the right (as we programmed it to do so). When we press left, it goes to the left (as we programmed it to do so). Everything works just fine!
HOWEVER -- here is the problem: When we put it into our computer running APPLE'S VERY OWN Apple DVD Player, the simulated remote on the screen has a mind of its own! When we press right on one button, it will go to the left. When we press right on another button, it will go up. When we press down on one button, it will go left. This is absolutely MADDENING! And this is Apple's OWN player!
We've also noticed that the simulator within DVD Studio Pro plays back the DVD verry slow... in a choked performance way. More so than we've seen with any DVD in the past. Is this part of the problem?
We are pulling our hair out over here trying to solve this! Can anyone please help?
Thanks!
Scott

An overlay style menu is a lot easier to create than a layer based one, and ionvolves just two flat files - one for the background (with everything on it that you want to show when buttons are not selected, etc) and one for the highlights (the overlay layer contains the shapes, text, tick, underline arrow or whatever that you want to show up when the button is selected).
These menus react faster, take only one click to activate a button and support the use of audio. They can't get as graphically rich as a layer based menu and if that is the prime consideration then I'd recommend using a series of menus linked together to go between the different button states, as this is still better than a photoshop layer based menu (which, incidentally, gets turned into a series of linked menus anyway as your disc is being built!)

Apple DVD Player will not launch

I have a B/W G3 Tower/Desktop as well as a G3 PowerBook (black laptop). Both run OS 9.2.2, QT 5.0.2, and Apple DVD Player v1.2.
When I try to launch the DVD Player on the tower, I receive the following on a pop-up window:
"Apple DVD Player cannot open because it cannot find the required hardware. Try reinstalling Apple DVD Player. (204)"
The following pops up when I try to launch the DVD Player on the G3 PowerBook laptop:
"Apple DVD Player cannot open because the required hardware was not found. If you have another application open that uses sound or video, quit that application and open Apple DVD Player again. If you are using a PowerBook that requires a DVD-Video PC Card, make sure the PC card is properly installed in the appropriate slot. (21)"
Both used to work but for some reason have abruptly stopped. I'm going crazy trying to figure it out. Speech is turned off and I don't have any other video or DVD apps open.
Any help would be greatly appreciated.
Thanks,
Dave

you may need to reinstall your operating system because it sounds like you dvd rom driver is damaged but there is a way around this to
go to google and search for a program called patch burn this application will reinstall a fress driver for your cd dvd rom drive but unknown if this will even work because if the file is currupted you may end up locking out the cd drive driver and your cd drive will stop working in os x and you will need to reinstall the operating system
but try patch burn first
