Chapters are completely unrecognized by Final Cut Pro X. The option to export an Final Cut XML file doesn't work, as the resulting file isn't supported by Final Cut Pro.
I even tried using SendToX (Apple's recommended XML->FCPX converter) but haven't gotten successful results converting any of the XML file formats that StreamUP outputs.
Requesting option to export .fcpxmld files or XML files compatible with SendToX.
