However, I think that's a gross oversimplification of it, though it is analogous to the people who say that their cable DVR "does everything a Tivo does", when there's clearly evidence to the contrary.
Discussion on this forum has shown that the TGOS data is not as full featured as Tivo's guide data (which comes originally from Tribune Media Services). According to other people here -- TGOS does not have new/rerun indication that the Tivo guide data (usually(*)) has.
Also, TGOS cannot carry every single channel that everyone needs in every market. This is technologically impossible due to bandwidth limitations. Tivo's data will have all channels (and will make new lineups for people, for example if an apartment complex gets their own special cable setup).
(*) There are some shows, such as the Daily Show, that routinely do not have guide data, and thus Tivo will record duplicate episodes. This can be worked around, but admittedly the workarounds are similar to 'manual recording' on these DVDRs. However, for the vast vast vast majority of shows, the data is accurate.
BTW, I have 2 Tivos and a Toshiba XS32. I have a lifetime subscription on my Tivos.. I am one of those who does NOT like a monthly fee for more services.. though special deals I've seen on the dual tuner Tivo have slightly worn down my dislike for more monthly fees, since it would be $6.95/month for me since I already have Tivos. In other words, that would be somewhat palatable to me, though I'd prefer the return of lifetime subscriptions.
