Advertisements No. At least not on this particular board. You can check at that other Site Which Must Not Be Named. Essentially, some of us have hot-rodded our S3 units to the point where we can run mfs_ftp, caller-ID, TivoWebPlus and a few other programs. But the usefulness is rather limited, and the videofile formats are different from the S1 or S2 so you can't do much with any file you might manage to download. You can, however, do speed comparisons. No. Not yet, at least. However based upon other threads and experiences it appears that the Bonjour-like MRV network discovery service code is included within the S3 system software. Currently the bits (digitial certificates) to "Allow" that function are disabled from the Tivo mothership servers. Again, no. Not yet. ComeBack is a feature I personally would prefer to see enabled -- uploads via pyTivo or Tivo.NET would be much more useful for me.
