Compressor error - Failed: Quicktime error 0

I'm sending my FCP sequence directly to Compressor and I'm getting this message after I submit: "Failed: Quicktime error 0". It's a 34 minute sequence. I'm using DVD Best Quality - 90 Minutes as my setting. I've googled this error and I'm seeing some folks suggest that there may be a corrupt file in the FCP sequence. Others say that it may be an insufficient RAM issue (not my issue). My questions:

- Has anyone seen this before? If so, how did you resolve?

- If this is due to a corrupt file, how would I go about finding that corrupt file?

Any help would be appreciated. I'm up against a deadline about to get into panic mode. thanks!
