Blue-ray burning via FCP>Share, 2 questions

Burning a 2 hour HD video takes approximately 15 hours to burn to Blue-Ray via FCP Share. Is this normal for you guys? I'm using Mac Pro, 10.6.8, Quad-Core Intel Xeon, 2.8 GHz, 10GB memory. All my videos this length take this long to burn so it wasn't just a one time thing, but sheesh!

Question 2, more importantly, after burning a video for 15 hours, I find the audio is out of sync by about 1 second. I'm not certain if this has always happened and I just now noticed it, or, if it only happened this one time. But, I'd rather not waste another 15 hours burning just to see if it stays in sync this time 😉

Any thoughts?

Thank you very much,

Eric
