There is also one thing that I wish to know for a long time -- how and why
transcode determines how to auto resize. 

The following are the auto resize examples that I collected (so as to
understand the how/why part), all are from avi source with DAR 1:1 and
transcoded DAR as 4:3. 

--export_prof svcd

 [transcode] V: import frame     | 576x240  2.40:1  
 [transcode] V: pre clip frame   | 576x450 (-106,0,-104,0)
 [transcode] V: zoom             | 480x576  1.56:1 (Lanczos3)

--export_prof dvd

 [transcode] V: import frame     | 624x256  2.44:1  
 [transcode] V: pre clip frame   | 624x480 (-112,0,-112,0)
 [transcode] V: zoom             | 720x480  2.81:1 (Lanczos3)

-Z 704x480

 [transcode] V: import frame     | 656x272  2.41:1  
 [transcode] V: pre clip frame   | 656x510 (-120,0,-118,0)
 [transcode] V: zoom             | 704x480  2.75:1 (Lanczos3)

 [transcode] V: import frame     | 608x320  1.90:1  
 [transcode] V: pre clip frame   | 608x426 (-54,0,-52,0)
 [transcode] V: zoom             | 704x480  1.95:1 (Lanczos3)

I was trying to figure out, if I don't use the transcode's auto resize, but
specify the resize manually from command line, how could I do that.

If you could explain it a bit some time later, that'd be really
appreciated. 

thanks
