Here are a few things to check when using Twonky Beam with Roku:
1) The mobile device running Twonky Beam and the Roku must be connected to the same WiFi network.
2) The Display Device list in Twonky Beam's right swipe out panel is an expandable list. Make sure it's not collapsed by clicking on the "Display Device" list header so that the full list of display devices is visible.
4) Twonky Beam discovers the Roku using SSDP as described in http://sdkdocs.roku.com/display/sdkdoc/ ... ryProtocol
. So if for some reason your router is configured to disallow SSDP or multicast traffic, discovery of the Roku will fail. If that's the case, you'll need to change your router settings to permit SSDP and multicast.
5) Discovery of display devices can take a little while after Twonky Beam starts, usually 5-10 seconds.
6) There is a known issue with Twonky Beam running on some Samsung Galaxy S devices that can delay the appearance of Display Devices for 20-40 seconds after the app starts up. But the display devices should appear after that interval and remain in the list for as long as the app and Roku are both running.
If none of those seem to be the issue, it would be useful to know the following info so that it can be passed along to the Twonky Beam engineering team:
1) Roku model and firmware version
2) Mobile device type and OS version
3) Twonky Beam version
