FCPX Export Compressor Settings QT Error -2045 and more...

Question

I have a 56 minute FCPX project that won't export. I've tried standard h264 and using Compressor settings for HD 720 for YouTube / Video.
Most recent error is QuickTime Error -2045 - can't find this error documented anywhere.
My console log last recorded for FCP this error:
12/8/11 11:39:26.447 AM [0x0-0x1ff1ff].com.apple.FinalCut: Exception raised cleaning up media server process System Error = 3 {No such process}IPC Server did not respond to message, Server process is gone
Other notable log entries include:

One of the two will be used. Which one is undefined.

(note that there are files in this directory and the transition works in preview in FCPX)

This is interesting:

Now prior to this last (4th attempt) at exporting I was getting this error:
12/8/11 1:21:39.618 AM Final Cut Pro: [01:21:39.618] <<<< VTVideoDecoderSelection >>>> VTSelectAndCreateVideoDecoderInstanceInternal: no video decoder found for 'XVID'
I found a decoder online but perhaps it's 32bit... however, this is just the last time; prior I was getting the no decoder error
1) What is -2045 error
2) What is the proper decoder to use for XVID
3) I do get a warning that there is missing media, effects, titles or generators - and I can see the inspector tell me that these are related to motionVFX Project 543 (see error above) but I can't find any instance of these effects not implemented. So, how can you quickly find any missing media (redzone) or other in a FCPX project without scrolling or playing through it. If something is missing I would expect that I should be able to quickly have my playhead jump to the missing media segment within my project. But I can't figure out how.
4) I need to deliver this project and can't get a suitable export and I'm on deadline, so any thoughts are appreciated. My ideal output is a file to load to Vimeo; secondly a good quality Quicktime movie would be nice. The file is about 50GB (my guess) I need less than 5GB and 720p HD
Thanks

Answer 1

From Crash Analyzer:
-2045 (QuickTime)
This error occurs when a file fails to write properly.
Suggested Actions
* If you were saving to a network drive, try saving to a local drive instead.
* If this occurs when exporting from Final Cut Pro, it can sometimes be caused by rogue plugins. Use Plugin Manager to disable third-party codecs for Final Cut Pro.

I would also recommend converting your Xvid files to ProRes before bringing them into FCPX.
