On these boards in particular, we need to rename or simply call the S3 as something other than the "S3". We all need to agree on the following: 1) The TiVoHD is a TiVo Series3 HDTV DVR and it is an S3 based "architecture" box. Even on the packaging for the TiVO HD, it has a logo on it that states "S3 Architecture". 2) TiVoHD is a different box than the original/premium S3 unit. So that said, what should the we call "S3"... I really don't care, maybe TiVo does and original S3 owners do, so I would like them to chime in. TiVoPony, is there an official classification now? How are you doing it internally? What does TiVo suggest/recommend? S3O (Series 3 Original)? S3P (Series 3 Premium)?
