VTDecoderXPCService is the sandboxing for video content in Lion. All things that are QuickTime related, audio or video, are sandboxed by this service.
The problem is caused by a corrupt video file, in my case it was a m4v file. And because the file was on the desktop, each time I restarted, or opened a finder window that opened to the desktop folder, the error would pop up.
However, some possible solutions are (each one, not together):
- Delete the file from the Desktop.
- Move the video/audio file to one directory (obviously, create them).
- Change the opening default app to another compatible, like VLC.
- In some cases, change the file extension to another, solves the problem.
