Streaming issue and no Twonky!

I am having issues streaming video to my Sony Blu-Ray player. The player sees all of the files, will try to play them, but will stall out after about 10 seconds. It will stream just fine from my laptop HD. My WD My Book Live is a 3TB if it matters and was just purchased this week. From what I’ve read, I need to try using Twonky, but from what I can tell, my MBL did not come with Twonky. HELP!!!

Hello, click on the link below for the steps to change to Twonky.
