Not a database issue. Actually it's related to a software change made to the channel a few months ago. Sorry I missed this forum posting! The required bug-fix is being processed now, a functional version of in-channel searching should be available later this week if Roku approves the update.
You are correct that Instant TV Channel is a set of developer tools for creating Roku channels. Usually channels built using Instant TV Channel are built & managed by 3rd-party developers who purchase services through Instant TV Channel. But for "Retro Tech Time Machine" Instant TV Channel built & manages the channel, there is no 3rd-party developer.
You can reach me at scott@InstantTvChannel.com if you have any other comments or suggestions for the channel.
