The image has "mosquito noise" around the characters which indicates that it's been compressed with JPEG or similar algorithm. You should definitely try to avoid any compression at this low a resolution.
I think your idea of investigating different video capture devices is a good one. It looks to me like there is horizontal "ringing" or an echo in the signal which is showing up as two ghost images slightly offset from each other in the X axis. With a clean signal you'd have a much easier time. If you are forced to deal with this, you can construct your filter matrices to operate in the X axis, but leave the Y axis untouched.
