Unable to burn a Blu-ray using FCP X'S SHARE

Hi Ken,

I attempted to burn a Blu-ray using FCP X's SHARE in my Pioneer Blu-ray deck. It failed. However, when I made a Master File and put in Compressor 3.5.3, it burned and played beautifully. My question is the FCP X SHARE Blu-ray program unstable or should I just plan to export a Master File and use Compressor to burn my Blu-rays?

Thanks,
Phil
