Welcome, K9Sports.

Plain Text Export plugin will export just about anything, but it requires a template to define each export. Some
sample templates are provided, and I suppose the
XML (Movies) template provides a reasonable starting point for exporting
movies in the format required by Roksbox. If you need something more specialized—like exporting episodes—you would need to create a template designed for that purpose. It would get the series information in the usual manner (a series record is exactly the same as movie record), but use a
subtemplate to get the episode information. Assuming the Roksbox can only display one set of information, your template would combine the necessary series and episode information for each episode.
Such a template would only be of interest to Roksbox users. Have you tried asking in the Roksbox forum?
