Quick Look: The TVCAST Roku channel is the companion to the "TVCast - Watch IPTV everywhere" Android and iOS apps. The app lets you send m3u playlist videos from the app to your Roku device. To use this channel, you will need to install the app on your Android or iOS tablet or smartphone, enter the URL of an m3u playlist into the app, then cast to your Roku device.
If you don't have the app installed and an m3u playlist added, there is nothing to be gained by adding this channel. It offers no previews or information. Additional information about TVCast can be found on the Google Play Store and iTunes pages for this app (see links below).
