I have both movies on Laserdisc, plus my own VHS recording of Battle for Endor from the original broadcast. The VHS I transferred to DVD quite some time ago. IIRC, someone around here documented some slight dialog differences between the tv broadcast and the early video release of BFE a long time back.
I *might* have an old toy magazine article with pics of the Ewoks and Droids lines, but it will take some time to actually find it if it's not gone for good.
A quick bit of Google fu did find this...
