Advertisements I have a DTivo that the Zipper process has gone wrong on. If I hook up a serial cable to the unit, I see a bunch of "buffer overruns" and other stuff going on. It takes several hours for the unit to restart - about an hour at the initial acquiring data from satellite screen and then another several hours for it to get guide data. Once it has completed the boot process, everything works ok. I've tried to re-Zipper without success. However, I've pretty much decided that I'm ok with returning this unit to the default software that comes from DirecTV and Tivo (unless someone has a fix for the issues described above). The catch - I want to make sure I keep the shows recorded on the drive. So... can I Instant Cake the drive to return it to an "official" version of software and keep the shows? Is there some other way of doing this or am I hosed completely and have to start from scratch? Any advice and/or direction will be appreciated.
