I think I have narrowed it down to Handbrake as my preferred encoder simply because it autodetects forced subtitles. I am still working on finding settings like i mention in my previous post. I am trying to copy the settings used by Fabio Sonnati (aka the guy who eats codecs for breakfast). If you don't know what I am talking about check this out.

720p @ only 500kb/s and it looks insane! I found a version (or an approximation) of his settings as applied to MediaCoder (for those interested they can be found here http://forum.mediacoderhq.com/viewtopic....sc&start=0 ). Then I did my best to transfer those to Handbrake so that I could take advantage of the auto forced subtitle detection. My concerns are more quality than anything. I don't really care about encoding time or size and I am running xbmc on linux so I have plenty of horsepower. I am not really sure how well this will work on the good old xbox but if anyone is interested these are the settings I am working with right now.
crf=16:qp-const=60:trellis=1:b-pyramid=1:qp-min=10:qp-max=51:qp-step=4:level-idc=51:me=esa:merange=16:keyint=250:keyint-min=25:analyse=all:direct=auto:nomixed-refs=1:8x8dct=1:analyse=all:deblock=-2,-1:weightb=1:bframes=5ubq=7:direct=auto:b-adapt=1:dct-decimate=1:fast-pskip=1:ref=5:bime=1
From the research I did before starting all of this I read that a crf of 17 or below would be indistinguishable from the original. Using mediacoder at crf=17 gave me a file that was smaller than the same movie encoded in autogk/xvid/100% and it did not have nearly as much "softening" so I was quite happy with that. I am now encoding the same movie with these new settings in Handbrake and hoping that the genius of Fabio Sonatti can make the outcome even better. It will probably take quite a while to encode but I will report back when it is done. Cheers.
