RafaMar,
Not sure if this is clear in the manual, but subtitles are ONLY implemented with creating DVD media so they do not show in the Compositor or regular rendering. There has been little interest in this methodology as far as I am aware. 

BT #280 is a feature request to implement usage of a commonly used ".srt" input file

Hello, I wanted to ask the veteran Cinelerra users a question to see if there is any way that the subtitles can be seen in the composition viewer.
