How good is DTV PVR compared to Tivo?
That's a very subjective thing.
How good is a Ford compared to a Toyota? Coke or Pepsi?
There's only opinions.
That having been said, the DTV R15 is a first generation product. It's got a number of fairly major software issues.
It is, however, in active development and has a fairly sizable commitment from DirecTV. When it is mature, it will probably be an excellent product.
The TiVo, particularly the R10, is what I would consider to be a fourth generation product.
It's very stable, and it's good at what it does. It is, however, at the end of it's design lifecycle by DirecTV's choice. (Regardless of how foolish that may have been, it's done.) It will not support new features going forward, and it does not support the same features as Standalone TiVos. It is, however, a hell of a lot cheaper.
I have had cable DVRs, Dish's 522, Standalone TiVo (HDR31202) and both an R10 and an HR10-250 and I'm happiest with the two lattermost.
