Hello to all in the forum, I am an AV technician involved in media control systems and I'm looking for answers or ideas to the following problem: we just trying to use the dbt3313 in a RS232 Set-up. I need to use a track search command to get defined tracks on the screen. We are using HD mpeg with 7.1 Audio. If we use a BD with the tracks we only reach the media folder structure of the player ( pictures, sound, movies ) F.e. track search 1 Play (single mode ) Has anyone tried it yet?
