Hi Andy,
Thanks for taking the time to do some testing in your environment.

My observations:
1. With the amplifier on and anti-alias filter off things looked fine.

I'll try to perform a quick test with my PVR-350 with NTSC and the YUV
capture device BTW.
OK. So my test setup:
a. DTV STB tuned to the SuperBowl :)
b. Composite out from the STB feeding my PVR-350/SAA7115 with an NTSC
CVBS input.
c. mplayer capturing raw YUV video from the PVR-350's

Hey Andy,
The visible effects of the anti-alais filter could possibly be:
1. Less range of color, if high freqs of the color get attenuated.
(Most people likely will not perceive this as most people are not that
sensitive to

With all that said, if you have a baseband Luma or Chroma signal with
strong spurious high frequency components (crappy source, or you're
overdriving the front end and getting intermods), then keep the
anti-alias filter turned

Hmmm. The AGC (or static gain level?) of the amplifier in the SAA7113
before the anti-alias filter may be set too high causing the clipping
(intermods) there. It may be worth looking at the gain setting for that

The better is to allow enabling/disabling the anti-alias via ctrl.
Whatever default is chosen, the driver may adjust the control default
at the board initialization, or even blocking the control when the
