Here's a live video link from Meron. (valid on Lag B'Omer 2008 only)
Here's another, lower quality-no sound, but more bandwidth.
Both only work in Internet Explorer, the pages are hebrew (doesn't matter for the video), and the first link si pretty much overwhelmed (so you'll be lucky if it actually starts).
Anyway, good luck!
