        Secondly, when ripping DVDs should one deinterlace the video? I have
        tried doing this a couple times, and apart form deinterlacing
        drastically increasing the transcoding time, I have not been completely
        happy with the results. If I really should deinterlace, are there any
        recommended filters I should apply?

    From what I've read, I'd recommend to do as little irreversible change
    during the ripping process as necessary.  Deinterlacing, subtitling, and
    many other filters can be trivially applied during playback, allowing
    them to be used only when needed.  Only if the change is too processor
    intensive to be applied on playback or will be applied in any case (such
    as clipping/resizing) or if you're encoding for playback on a specific
    device would I recommend doing it at rip time.

Hi
The trouble is, encoding an interlaced movie will prevent the codec from giving
good results, for while codecs are designed to analyse a picture as a whole and
then compress it, they will have diffulties dealing with two "mixed" pictures. 
So the result won't be too good looking.
please have a look at http://www.bunkus.org/dvdripping4linux/single/index.html#
ripping_interlace
    

This depends entirely on the codec - xvid, for example, has an
interlaced mode in which case it will deal perfectly well with
interlaced video
  

That sounds good to me :)
How do you do that (I didn't see anything in the configuration options accessible from dvdrip, but my xvid4conf might bo too old : 1.12) ?
