Your PVR 250 isn't capturing digital TV; it always captures analog
signals. They might have been digital up to a cable box.

A number of options occur to me:

- Check signal strength and quality just before your PVR250
- The IVTV driver might have problems; what revision are you
  using?
- Could you get an ATSC tuner and see if that gets the channels
  you need with adequate quality? ATSC captions seem to be much
  more reliable than NTSC. (This only applies if you are in the
  US).
