Apparently, it auto-updates itself to the latest dash so the audio/font hacks are plugged for the time being. I don't use live, so I'm not concerned atm.
In fact, I ftp'd in this morning and renamed the xodash directory on C: to xodash_, so the Live option on the m$ dash isn't available, yet I'm still running dash 4920, and my audio hack is still good.
Let's just see if games start auto-updating from the dvd in the future, hmm...
