Is it correct to specify the fps of 1080i as 60000/1001? It should be 
set to 30000/1001 (29.970) automatically so you shouldn't have to 
specify it on the command line.

I've used the tfields filter with the default option like this to 
convert 1080i to 480p and I've been very impressed with the results.
