adywan said:just search for "star wars avchd" on demonoid and you'll find them
That was the first thing I tried, which was how I found ANH, then I tweaked it to search for Empire.
Edit - OK, searched for "adywan" and I found it. I figured they would be named similar though, which is what was confusing me. ANH said "STAR WARS IV" but ESB said "Star Wars Ep 5". ANH also had "AVCHD" in the title, ESB didn't.
