I'm currently investigating the different TiVo formats and documenting it on 
the wiki. Are you referring to ty streams or the encrypted TiVoToGo 
streams? And to be sure there's no misunderstanding, you have a mostly 
working demuxer for ffmpeg already?

As for sample files, our repo at samples.mphq is a bit lacking. Perhaps 
somebody reading this list could upload a few other samples? Also, there 
are no TiVoToGo samples at all. Might be tricky because of the private 
Media Access Key needed to decrypt them, but perhaps something can be 
arranged off-list. Or somebody can donate a real device with recorded 
content on it :-)
