Plex, now triply confirmed for the platform, is just weeks away as TiVo begins rolling out software version 20.4.7 to Premiere and Roamio units. Its ultimate usefulness and quality will likely be governed by launching as a native app, like Amazon Instant, or living within the Opera TV app store. Neither Plex and TiVo have yet to respond to my inquiries, so your guess is as good as mine. Regardless, I’ll go ahead and assume the Amazon Fire TV will retain the crown of top Plex client… but there is something to be said for Input 1 access to the important stuff. 20.4.7 also sets the stage for iHeartRadio and Vudu (finally on Premiere). You can see the release notes above, copied from TiVo’s revamped support site, and sign up for the Priority List here.
