Well, IMO that delay code in the ttxtsubs plugin should be removed when 
PTS code has been merged into the repo.

How about adding a STC offset setting in these "non working output" 
plugins with a little help of latest PCR value and the system clock?

I'm against these kind of dirty hacks in the official VDR code tree, but 
the current dvbsubtitles code in VDR could be refactored to be 
replaceable with a plugin. Afterwards the reel plugin could reimplement 
it with any hacks needed.
