Dan,
    Closed Captions are currently broken for PVR-250 & PVR-350 in IVTV 
drivers over version 0.10.1  It works OK with a PVR-150 or PVR-500
Currently, version 1.2.0 is included with Kernel 2.6.25, so that was 
quite an old version that worked.

This was the last update from Hans

To find your IVTV version, type dmesg |grep ivtv in a console window. To 
find your kernel version, type uname -r

If I understand right, you have digital OTA stations, picked up by a US 
government DTV recevier box and fed into your PVR-250 via an s-video cable.
An ATSC capture card, like a PcHDtv or an HD Homerun, would pickup the 
digital OTA (with captions) and capture it directly, bypassing the DTV 
converter box.

I'm in Canada and I wish I had some ATSC coverage, I'm using satellite 
tv right now, so I'm waiting for mythtv support of the HDPVR-1212 (and a 
faster frontend to play the h.264 streams)
