ok, I finally got a chance to look at the HDNet pattern...
I SERIOUSLY have to question that pattern. here is what I find on my tv.. note this is switching between 480p and 1080i. Also note that some of this is the oddity in my TV, which I have remarked where applicable.
Going between 480p (which calibrated with my DVD playewr is spot on at 5% overscan) and 1080i, the Tivo shows the vertical overscan to be set at 5% according to the HDNet test pattern. This is confirmed by switching back and forth between 480p, which I KNOW is set at 5% and 1080i. They are showing for all intents the same overscan (though 1080i seems to be shifted down ~1% which could very well be my TV, i.e. above show slightly less than 5%, below shows slightly more than 5%). So vertically there is no question that MY Tivo is right where it should be..
Now horizontal is interesting... very interesting. at 1080i my TV is showing 12% overscan.. which is insane... I mean seriously, WTF!?!?! But here is the clincher, at 480p, my set is also showing around 12%. Again my set is shifting the image slightly horizontally between 1080i and 480p (in this case to the left by about closer to 1.5-2%), but the actual width appears to be the same (the shift appears uniform in the same direction on both sides).
MY conclusion? There is definitely something amiss.. However, I am still not going to say it is the Tivo...
to help out, can someone tell me the next time the patterns are going to be on HDNet? Just for this test, I will resubscribe my E86 just long enough to check the pattern and see where it sets up on my TV.. If I see the pattern on my E86 at 12% as well, the problem squarely rests on the HDNet pattern.. if I see the pattern on the E86 come in at 5% (seen as though my HD and 480p inputs seem to be fairly in line with each other), then it is obviously the Tivo..
I will let you guys know.
I also have the pattern saved on my box and will take it into the bedroom this weeekend and check it out on my 32" sony where I know overscan is also dialed in around 5% all around.
