From Galleon HME Beta 3 released:
Galleon is a next-generation version of JavaHMO. Unlike JavaHMO, Galleon uses the new HME API that TiVo has released.
Unfortunately I don’t have a non DirecTV Series 2 to try this on. Maybe if I come up with something cool for TiVo’s HME contest, then I’ll buy a third TiVo.
