So.. this is probably a dumb newbie question.. but I've recently purchased a blu-ray player, and have successfully used other software to burn DVDs with AVCHD video that plays on it.  I am now trying to use Studio 9.0a platinum, with no success.
(Getting an error about disk speed not matching - even though I've tried both 2.4x and 8x DVD+R DL disks in my DL Disk Writer)
What are the formats I should use (I tried the default), and what do I need to know about disk types for doing DL disks?  
Thanks,
-Kevin
