Hi all, exciting news! After more research, digging, and tinkering, it’s become clear to me that these DVRs and receivers can run just about any OS you throw at them—well, sort of.

For example, We recently got our hands on a Scientific Atlanta box running a TiVo‑skinned OS. I hooked it up to a Suddenlink cable CMTS and managed to get it running in Cisco’s SARAH environment. Before that, of course, we scanned the drive to see what we could uncover. Unfortunately, our host machines didn’t play nicely with the drive and kept crashing whenever the TiVo data from that Scientific Atlanta box was accessed.

This was all done in coordination with my good friend Mixer, whom I’ve known for a couple of years. Together we’ve tackled many interesting projects—switching between our emulation project (currently shelved due to technical constraints that require further research to make it work as a JIT compiler) and reverse‑engineering ISP cable systems on the firmware side, using publicly available resources.

Along the way, we’ve come across boxes running Flash Player, Opera browser, and other unexpected software. All very fascinating details! I can’t share too much just yet—I have to keep you on your toes—but I promise there’s more to come.

As a teaser… here’s an image.
