Has anyone else had trouble seeing twonky on their xbox 360 since the dashboard udate?  it no longer pops up for me when i go inot my video, but every other dlna device in my house sees the drive without any issue.  Please help if anyone knows what the problem is.

Same thing  happens to me, I fixed, restarting the My Book Live, after I restarted, I turn on the Xbox 360 and it was detected.
