Can I copy video from my Mac to the Roamio to watch on my Mini? I downloaded the old TiVo Desktop, did the terminal hack to enable video sharing. The Roamio sees it, but not the m4v videos I copied to the shared folder. I looked at pyTivo, but from skimming the SourceForge page, don't understand how to install it. And it seems to be a streaming system. I'd be happy to push videos to the TiVo to watch, but streaming is ok. The videos of interest are transcoded by Handbrake in the AppleTV settings (for iPad viewing).
