Everythings been working fine, better then fine with your compression settings and into DVDSP. I'm exporting into Compressor out of FCP a sequence that's 60 minutes. Compressor opens and prompts "can't preview movie FCP is busy". I ignore it and submit but compression fails. This never happened before. I've renamed my seq, I've tried exporting a QT to desktop and opening Compressor from there but to no avail. Any suggestions?
Try killing the Preferences for Compressor and Batch Monitor (User>Library>Preferences>com.apple.compressor.Compressor.plist, com.apple.Compressor.CompressorSharedService.plist, and com.apple.BatchMonitor.plist). It's also good to reset the database in Compressor, and clear the history.
I would quit out, trash the preferences, go back in, reset the background processing (in the Compressor menu) and clear the history.
Make sure no jobs are still running in the background by going into Batch Monitor and expanding all the clusters.
