Re: Interlace Noise (field swapping?) on Pinnacle PCTV

    I own the same card as you, and found that my picture quality was pretty
poor until I hooked up one those radio shack cable TV amplifiers.  The
problem wasn't very pronounced in fbtv, but when I encoded mpegs/divx's it
was fairly noticeable.  Try going and picking on of these things up, and if
it doesn't solve your problem you have 15 days or so in which to return it.
