Agreed. I mention it simply because AFAIK DVD recorders converting from 
analog will almost always produce interlaced files. However, more important 
is that the entire process of converting analog tapes to digital is full of 
pits and perils, and the conversion artifacts will play hob with any 
processing (like de-interlacing).

The best route, of course, is to capture into a lossless format and process 
from there. May not help the OP.
