Cant get DVD to verify!

[Anna Conlon]

I’ve just tried to build and format another file with DVD stuido pro as a test to see if i get and problems and this message appeared

The file is locked and cannot be opened for writing. Unlock the file and try again.

Check permissions on ALL files used in the project.

How is the hard drive that you are building the project formatted. These are not normal issues

In your first post how exactly are you formatting the disc. There is no verification in dvdsp.

[Noah Kadner]

Yeah I haven’t verified a disc since I gave toast the boot a few years ago…

Hi everyone and thanks for the reply’s

Terry I’m not sure how to check the permission? can you explain further?

Michael And the method I’m using is a ken stone method I build and format the disk to my desktop and then used disk utility to burn the disk at the slowest method possible 2.4

In a desperate measure I’ve watched over the samples that failed (hoping they would work and they work ok except in certain parts. I have one main mpeg (which played fine) and then a 2 smaller mpegs lined up together on the time line and I don’t think it likes it. I’ll try exporting a video stream mpeg again even thought it didn’t really work the last time …….but desperate times

I’m not a big fan of some of the stuff on Ken Stone’s site with regards to DVDSP. That process is just crazy. DO the Build and Format to a DIsc, DVDSP can burn the disc just fine, burn at slower speeds is not necessary these days. Just buy top end media that is rated for 8x and but done with it.

It is never a good idea to string m2v videos in the same title set, it should always be encoded as a single video.

You also have not posted process of creating the m2v files, what audio codec you are using (should be ac3) and the bitrate of the video.

[Anna Conlon]

I’m using AC3 not sure about the bit rate what should it be exactly do I set this when I”m in compressor?

What media do you recommend I dont mind spending as it would save so much time and pain

“You also have not posted process of creating the m2v files” I create them in compressor 90min best DVD ….I would re extport the file but the problem is i dont have the originally Quick time so i’m trying to export the mpeg to on single video stream from DVD studio pro hope full this will work

I switch to the ken stone method when I was having problems with disc failing when they went out to customers even though the burn process appeared to work

[Eric Pautsch]

Try the Michael Sacci method 🙂 Check your bitrate in Compressor’s Inspector. Use AC3 audio as well.

This particular “Ken Stone method” is very sound and true. Nothing wrong with it. I do the same thing and here are the reasons why:

1. The simulator in DVDSP and the software DVD player can play back differently. (Rendering of menus, transitions, pauses, breakpoints, etc….) So you must proof your final project off a DVD disc or DVD image on a hard drive.
2. The build & burn to hard drive is much faster than burning a disc.
3. If I need to burn a second or even third copy for a client, I don’t need to rebuild or risk having any changes occur. I just burn from the master .img file.
4. I can FTP the .img file for duplication.
5. I can archive the .img file.

All of this from one single process…its much faster.

Now, back to why your disc won’t build correctly. You post states that the error message is that “the file is locked”. Unfortunately, we can’t determine if that file is an asset, the DVDSP project file, or the temp .img file. So we have to try and tackle them all.

1. Asset file is “locked”.
Check the file permissions for each asset used in the project. (CMD+i or right-click and choose “Get Info”) Make sure “you can Read & Write” for each file and that the “Locked” check box is NOT checked.

2. DVDSP project file is inaccessible.
Try to do a “save as…” for the project and see if the new file works.

3. Temp file is unhappy.
Make sure you are writing your .img file to a happy place. If you have “FileVault” turned on, do not write the .img to desktop, documents or other user specific places. Instead write to a common area, such as the base directory (“c:/” or “Macintosh HD/”) (You can check “FileVault” settings in the System Preferences>Security.)

I wouldn’t do these in this exact order though, now that I am looking it over. Option 1 will take the most time to do. I guess I would try Option 2 first. If that doesn’t work then try Option 3, followed by Option 1. If you perform all three and still have trouble give us a hollaback.

One of the only things that has caused DVDs to not verify for me lately has been moving the computer while it is burning – something that should (obviously) be avoided. You never stated what sort of computer you’re on, so if you’re on a laptop and it is moving at all while you’re burning, that could do it. Hopefully unless you’re in an emergency situation on location somewhere that would never happen, but you never know.
