If i get install the Nexus & with the plex app and use it to stream the content to the roku box ( $50) version would that work always for audio video and images? And when I have the roku and the tablet set u on the same wifi network...would streaming from my nexus to the roku use my data or bandwidth?
You would install Plex server on a PC, and the Plex media channel on the Roku, and/or Plex media app on the android device. With this setup, you could stream videos from your PC, or from the Internet (if using Internet channels like Hulu) to either the Roku, or to your Android device. The Roku uses your wifi network, android devices can use wifi or cellphone data.
If you are trying to stream a video saved on your android device to your TV, then you don't use Plex. You would need Roku juice installed on the android and on the Roku box too. Note, I only tried this with their demo app, which is limited to the first video and I did not see the Transformers video in the list. I don't know if that is a demo limitation, or if the Roku juice app can only stream videos you record on your android device.
