TiVo DVR to PC? - DirecTV DVR

For TiVo DVR to PC?, relating to DirecTV DVRs and receivers. I want to back-up my recorded shows, playlists, etc. to DVD via my computer. I have both desktop and laptop units? I also have both Win XP and Mac OS. Is there a device/software that will allow me to take the output from my HD-TiVo DVR HR10-250 and feed directly to my PC, where I can then record to DVD? I've look at some stuff from Pinnacle software, but I'm not sure.
