Trying to get some help reducing the size of my final encoded Mp4 files, doing the following:

I either rip from mactheripper or HandBrake (I prefer the latter). HandBrakes help files are vaque. Perhaps someone could point me or explain step be step. And then I take either the Video_TS from MTR and convert using Kinoma producer, or take the HandBrake file and convert it with producer. BOTH ways give me HUGE (400+ mb) files. I am sure I can get the final down to a smaller size and still not give up on quality on my Treo?
Any help would be greatly appreciated. THANX
