Odds/Evens is a total of 4 tapes, two 'odds' and 
two 'evens'. It is available on VHS and DVD, 
though the DVDs are only available in the R2 box 
set V. IIRC, only the Operation Meteor II 
contain the additional footage, the Operation 
Meteor I tapes are sort of a recap of the series.

Best of luck in locating them. I bought mine off 
a Japanese used media store about two years ago.
