Various types of video feeds and playlists can be used in Instant TV Channel without modification.
But because of the way that MRSS feeds and playlists are assembled,
it may not be possible to use all of the features within Instant TV Channel for videos contained in feeds or playlists.
Additionally, because each individual Roku device performs the work of deciphering each MRSS feed or playlist,
larger feeds and playlists may perform slowly on older or less powerful Roku devices.
In order to eliminate these disadvantages you can import videos from certain types of feeds and playlists into Instant TV Channel to use as individual video items.
When a video feed or playlist is imported into Instant TV Channel,
the videos contained in the feed or playlist are copied into the "native" Instant TV Channel format which has many more features and options available than the feed or playlist.
The imported videos and metadata can be modified or re-arranged as desired.
After the videos have been imported, the feed or playlist is no longer needed and can be deleted from the channel.
