Basically I made the best of what I had. I still don't like the CG robots, but what can you do? It's certainly better than Dex, the four-armed CG cook.
And thanks so much for all of your tips on where to find the 3po dialogue. I've ordered the OOT DVD's, which contain the 04 editions, so I'll be able to extract center channel from that. I'll also check the radio dramas if I have time.
It's coming, guys! The end is in sight... I'll probably have an approximate running time for this by mid-October.
