This is another item that really has nothing to do with the driver.  
I'll bet that the MythTV wiki talks about this.

But since I'm already posting a reply:  You're talking about in-band 
program data which is not nearly as rich as you'll get from 
schedulesdirect.org.  The in-band stuff is generally only at most 24 
hours in advance; with scheduledirect MythTV will pull in data going out 
2 weeks.  Also in-band is very terse while schedulesdirect gives you a 
feed into all of the TMS program synopses.  It's WELL worth the 
$20/year.

Oh, if you do want to do in-band data, it should work fine with the 
HVR-1950.  Unlike analog broadcasts where such text content would be in 
the VBI data (which the driver doesn't support), for ATSC reception all 
captioning, program info, etc are just data packets in the ATSC byte 
stream.  The pvrusb2 driver just facilitates pulling down the byte 
stream; the actual content is irrelevant to the driver.  So receiving 
in-band program data should work.

Now go search google to see what people say about schedulesdirect.org.
