2-way repeated measures MANOVA

Hi, I have some motion tracking data that is in the format below:

data=(samples,q,v,d,p)

where samples = sample number (1:60000)

q = value of position in each sample (X,Y,Z)

v = 1:2, video condition, 2 levels

d = 1:2, difficulty condition, 2 levels

p = participant number (1:12)

I would like to run a 2-way repeated measures across the 2 crossed conditions and for each participant in each value of position data.

I have done this before in SPSS, but this was only with a small sample and with a mean of the 60000 data points for each position (not ideal!)

The mathworks literature is a little sketchy on MANOVA, so I was wondering if anyone has any idea of how to do this? Worst case scenario I'll have to extract and run in SPSS but that is a last resort option only!
