It would seem his goal is to go to AVI, since the destination format is  
MPEG-4.

Now, about worrying about telecined anime: he's going from a VCR to a  
TV Capture Card to an AVI file is my guess, so it would be a normal  
interlaced stream, I highly doubt telecine is going to come into play  
here. Deinterlacing it shouldn't do any damage.

He's my recomendation for a command line:

mencoder (TV options here, I assume you know what to do) -o (File Name  
Here).avi -ovc lavc -oac mp3lame -lameopts br=128:abr -lavcopts  
vbitrate=800:vcodec=mpeg4:vhq:v4mv -vf lavcdeint

You may need to specify your resolution somewhere in there, and feel  
free to tinker with the audio settings. I've used those settings for  
going from my TV capture card to AVI files, as well as even going from  
DVD to AVI files (Yes, animé sources included). I've found that  
mencoder normally handles the telecine issues itself, and gives me a  
nice progressive scanned AVI files suitable for playback on most any  
MPEG-4 compatable player.
