I have build 7000 of Win 7 Beta 1 as well and I was just messing with this the other night and would ripping my hair out lol, its very picky on what it updates I guess. I had to delete all files in that folder after stopping media share service under task manager. I then restarted WMP and i disabled sharing on my music folder b.c it does that first and have much more music than movies so it wouldnt take so long. But yes this is no doubt a bug in the beta.
All I had to do was start WMP and go into the Video library. After a few seconds it would start to update the shared folders and add new additions to the list.
