Thanks for any consideration in advance! Basically, Navi-X is a big funnel of video, audio, pictures, podcasts, text, and media in general. People link to stuff on our site and it shows up on a proprietary Navi-X playlist. All you would need to do is create a parser for Navi-X .plx playlists and the rest is cake. Here is an example of the home page of our Navi-X portal..

rating=-1.00Here is a link to a screenshot of what the playlist above looks like in Navi-X...
http://www.box.net/shared/sxsxbjdbx2g6ssik9h1pBasically, type represents the type of media (video, audio, image, rss, txt, html, etc.), Name is a text label for the item, thumb is a preview thumbnail fo the item, URL is the item you wish to play, processor is basically linking to a serverside scraper for processing URL final destinations for injection and playback into the player, player is an override option for dvdplayer or mplayer in XBMC and rating is a rating for the item from other users. If you can make a parser read the output of a Navi-X playlist, it's golden. Then just display a list based on parsings.
Hopefully reading the contents of a playlist will help you find easiness to porting this into a function for Serviio... please don't just say no for the hell of it peeps! I know you would like to get access to almost everything on the internet in a quick and easy to use search and browse tool for streaming media and we already have 245,000 users who help contribute links... cmon!
