whats a good bitrate to encode at for Anime on DVDs?

[Tekka]

I have a bunch of animes that I would love to put on DVDs but so far I'm pretty dissapointed with the quality after wasting like a week and 10 dvds trying to figure out how to deal with the overscan issue...

I encoded about 10 episodes to DVD at around 2300 bitrate and that was ok at first but i noticed when there was some fast movement on screen the video became extremely grainy but at slow moving scenes it was perfect...

I tried encoding 3 episodes to put on a single dvd just to see how it would do and found that it's PERFECT.... I think it was around 8000 bitrate...

Now my question is I can't waste anymore DVD or time testing and would like to know just how many episodes can I put on a single disc without it becoming grainy???

Oh yea i'm using Tmpgenc Xpress and Tmpgenc DVD Author...

352x480 interlaced (do not crop out overscan, cover it with black if you insist) 2.5 avg, 4.0 max

I have 20 eps on 1 dvd. I used vcd bitrate of 1150 and am happy with the results. On anime you really only need about a average of 1800-2000 bitrate and anything more is a waste of space, but thats just my opinion.
