Dave Zatz has updated his handy TiVo To Go guide to include instructions for moving your recorded TiVo content over to Sony's handheld gaming device. It's a little patchy, with a few steps of manual transcoding and the like in between, but I'm sure someone will build a nice all-in-one tool soon enough. Until then, Dave's got the basic steps (and plenty more info for transferring your TiVo To Go content elsewhere, not just the PSP).
