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.
