I don't know if the PVR-x50 cards are even capable of providing raw 

As far as the closed-caption (VBI) data goes, see below...

Currently, if you want the VBI data, you need an analog tuner card that 
uses V4L.  The VBI support for the PVR-x50 cards is being worked on by 
the ivtv driver developers, but it's not stable/finished AFAIK, and 
it's not supported by Myth yet anyway.
