For a post in a.b.dvd you definitely need the name of the rar-files so you can search (instead of retrieving all headers). I usually post there too, wasn't aware that a lot of providers don't support it. I think it's better to keep a.b.starwars purely SW related, that's what it's for. A couple of groups I have good experiences with: a.b.boneless, a.b.cores, a.b.dvdr, a.b.ftn, a.b.misc and a.b.movies.
