OK, I tried this, and the TV (Panasonic 27" CRT) shows
perfect captions.

Well, there is only a little bit of ghosting and snow.
 Moreover, dbx-401 shows perfect captions as well. 
Moreover, zvbi-ntsc-cc -c -d /dev/vbi1 (on PVR-350 vbi
device) shows perfect captions as well, hence my
suspicion that MythTV decoding is broken.

I tried swapping the feed to dbx-401 and PVR-350,
exactly same results.

I'd really like to get to the bottom of this.

Thanks,
