There are some "flags" in the Internal Tivo database (MFS) that indicate whether your Tivo is a older one that was allowed to work without guide data as a VCR or not

Well, that's something I didn't know! Of course, it's becoming apparent that the older I get, the less I know. I mean, when I was in High School, I knew everything.

How could I tell if my TiVo was an "older" one? It is just about two years old now...
