So you have two problems:
1) Your TV-out quality is not so good.
2) Your PVR-250 is giving you bad quality as well.

The first can be fixed with a cheap GeForce card (as someone else already
suggested.)
The second *may* be fixed by updating your ivtv driver to the latest
version, and trying to reapply the visual adjustments with test_ioctl.
