Can I stream from my original Premiere?

It seems that the Tivo Online is only for 4-tuner Premieres. I want to do in-home streaming of our original Premiere.

I don't want another Tivo, since I have lifetime on the Premiere and 2TB storage.

If Tivo Online streaming won't work, due to the limitation of the streaming devices only working with a 4-tuner Tivo, my only other thought was that I could pull the shows and dump them onto our Plex server. But this seems a little bit convoluted....

Any other ideas?

Thanks.
