Paul,

I tried but I don't see any difference after jump back and replay.  But, I
did see some interlacing effects and my system does have overscan correction
so maybe it isn't fair.  The other huge factor is what I watch on this TV.
 Jepordy, The News Hour, This Morning with George...   Bunch of talking
heads mainly.  Plus, this is an old CRT TV and not a high resolution
monitor.  My main interest was for my projector which is 720p but can take a
1080i input.  I should probably try looking at 1080i with it but too much
work for right now.  I don't think I am helping with your question but did
want to get back to you.
