Advice On Re-encoding Animated DVD

[dodle]

I'm copying an animated TV series from DVD to my computer. The DVDs are encoded at 29.970fps, which I find strange because animation usually uses 23.976fps. Anyway, what I have done is de-interlaced and re-encoded it to H.264. Now it is set to 59.970fps, which I think is higher than what I want. I'm seeking advice on whether I should leave it at that or change it to one of the lower frame rates.

----- EDIT -----
Another question: Do you think that I should be encoding to H.263 instead? This is just to have copies of the videos on my hard drive.

Note: I used Avidemux with the Yadif filter using the bob method to de-interlace the film. I think the bob method preserves the actual 60 fields and converts them into complete frames. I'm guessing that the temporal spatial check would halve the frames and give me the 29.970fps.
