The Tivo has hardware mpeg encode and decode, effectively a pvr-350 and possibly a bit more than that, also some OSD assist hardware probably. And the UI there is often annoyingly slow. They also have put in sufficient kernel mods to get real time response on the limited A/V work they have to do. The requirements for HD-Myth have dropped a bit from a P4-3ghz (which was a good recommendation for 0.16 with no hardware mpeg decoding assist), some people report success in more like a 2ghz range though that is pushing it. xvmc isn't full hardware mpeg decode but it could drop your requirements. Myth is a bigger program than tivo, which was designed to be small, in low ram, using tcl and a much simpler database package, so I doubt it would ever run a 33mhz machine even with full hardware mpeg encode and decode, but for sdtv you can certainly manage with 2 generation old systems.
