DTD validation failed - importing from Pluraleyes

I had this issue because I applied a "Loudness" to one of my audio tracks before sending the XML to PE. Remove all adjustments before sending to PE. This should fix it. Here is what Red Giant told me.

DTD errors are generally encountered in the round trip back to Final Cut Pro from PluralEyes. It is usually a symptom of how the media was imported into FCP initially. You will want to make sure that there was not any audio enhancements made or any other metadata, such as keywords. Additionally, you will not want to include and effects, markers or in/out points. Essentially, any adjustments made by Final Cut Pro will be seen by PluralEyes as an edit and can affect the exported XML.

Can you please try reimporting the media into FCP X, create a new project/library without modifying anything then export to a new FCP XML file and try your sync again?

Alternately, you can start your project in PluralEyes first, syncing and then exporting to Final Cut Pro. This should eliminate any extraneous XML confusion from the round trip process.

If you are still experiencing the issue with a new import/sync, supply a problem report and I can continue to assist from there. To generate this report:

• Setup your project as you've been doing in PluralEyes
• Click Synchronize, then click Export
• After that's done, save the PluralEyes project and click Help > Report a Problem

Save the report, and you'll have a .zip file on your desktop. Attach that .zip file along with an exported XML of your synced sequence and the FCP XML generated from Final Cut Pro to your response, and we'll troubleshoot from there.
