Honestly, I gave up on the whole Roku thing, and simply picked up a HDMI stick computer to act as my streaming hub. Upgraded it to Windows 10, used Kodi (XBMC) to play any media I had, used the integrated Netflix app in Windows 10 store to play Netflix, youtube, etc. As it is a smart TV, I use the device itself for streaming Amazon (as web based streaming on the stick is in a much lower quality.)
I have all my video library stored on an external hard drive which is easy to clone, and use an HD HomeRun to capture the over the air broadcasts which can be watched and recorded with Kodi’s extensions.
If you video library is DVD, how did you “record” it to your external HD?
