Tonight, while checking to see if there were any new updates to TiVo Tool, I stumbled across this thread on the DealDatabase Forums (where all serious TiVo hacking seems to get discussed), about the inclusion of a tystream demuxing module with VLC 0.8.2. Also linked on the thread is a module for streaming from TiVo to VLC.
Geek speak aside, what this means is that I can now stream shows from my TiVo straight to VLC player on my Mac. Coolio!
The trick for me was to figure out what invocation to use under the File -> Open Network command. After following the instructions on the DealDatabase thread, choose Open Network from the File menu, and enter tivo://192.168.0.10/plist into the first field in the dialog. (You have to replace the IP address with the IP or host name of your TiVo unit.)
Then open VLC’s playlist, and double-click the show you want to watch. Easy as that.
If you have trouble downloading the tystream and vserver modules for VLC, post a comment, and I’ll hook you up.
