I have not tried this out before, though I'm going to be experimenting on this too. I'd recommend that you approach some of the fansubbers, such as BakaMX, about how to create low-fps episodes. BakaMX's Love Hina releases were at 15 or 20 fps.

The filesize will be affected by the bitrate you apply. I doubt the fps will affect it.

A simple way to cut the fps in half would be to use the decimate(cycle=2) filter in vdub/nandub.

http://sauron.mordor.net/dgraft/decimate.html

That should work ok with the subtitles, as long as you apply the subtitles filter before the decimate filter.

Well assuming that the Anime you are encoding, was originally made at 12 or 15 fps, and just had every frame doubled to achive NTSC playback, there should be a slight quality gain (at the same bitrate), but probably not very much, the divx codec is very good at encoding identical frames.

Default about Love Hina

I'd be really hard to find it around the big groups, since it's been licensed and many servers have thus stopped serving it. Does not Kazaa or such have them? I do know a few channels on irc that might have them, but is your friend comfortable with using irc?

Yes he is. he and his clan even have their own channel on quakenet.
I believe it's rather hard to find them on kazaa to at least the episodes he's missing.

I can ask him today which episodes he's missing
