The RealMedia/SIML document issue is just confusion on the part Windows. It shouldn't cause any problems : SMIL is another markup language for authoring accessible multimedia presentations. Current versions of the Quicktime Player and the RealMedia Player support SMIL. SAMI is similar to SMIL, but was developed by Microsoft and is supported by Microsoft products. This can create confusion because SMIL files and SAMI files may both use the same (*.smi) extension. It does mean that you are processing the .tivo files to create sami files but there is a problem with WMP interpreting the contents of the sami file. I think I know the cause but it is too messy to talk you though a fix so you will need to wait until I post a new copy of the program to my website. (one of the reasons I indicated that this isn't yet ready for wide distribution - you are all guinea pigs right now). I will let you know when it is ready.
