I have recently purchased a HD TiVo and was excited about the TivoCast option as I could see the great potential in the convergence of traditional television and Internet video. But, for the most part, I have been appalled by the poor selection and quality of the TivoCast options. Sure, there are a few good shows (e.g. Cranky Geeks, CNET), but given the mind-boggling number of high-quality Internet-based shows (e.g. Revision3/Diggnation), why has TiVo not been able to bring us these better options? Any thoughts?
