Keep us posted, but you should probably checkout CVS, and compile the 
win32/experimental projects. There is one called encoderwin: it works 
from the commandline and you can redirect output, for example

encoderwin myvideo.yuv myaudio.wav > myvideo.ogg

You should also compile splayer, it is functional for forward playback, 
but no seeking at this time.

If you want more control over encoding, you can maybe encode your videos 
using the VP3 codec in AVI format, and use the experimental/transcoder 
to convert the VP3 track to theora without recompressing. There is an 
utility (avi2vp3) included in the transcoder directory that will pull 
out the vp3 stream from an avi file, and this is what you should feed to 

Everything pretty rough at this stage, but functional. Keep us posted,
