I clarify.  First you grab from your tv (or dvd, or whatever device) and
create a high-quality .avi - with a vbitrate of 1500+ or so, enough so
that you see no quality difference from the "original broadcast".  So it
should be similar to the step that you first described. 

So, after this step, you have a high quality copy of your "original
broadcast".

Then, you reencode this .avi to reduce file size, using 3-pass encoding.
