Ok edit. I played with the settings alot this morning. On OTA, I get what you suggest. Tru 16:9 content is 16:9 content, and 4:3 is stretched to 16:9.
Its the cable box output that is wierd. I should say that I basically put the maggie in place in the exact same place my panny ez-27 was. On the panny regardless of settings of tv or player I always got a 4:3 image, with 16:9 embedded in 4:3. The input on both players is s-video and audio from the SA 8300hd dVR. On the maggie I now get stretched 16:9 content embedded in a 4:3 image, or basically what looks like a 2.35:1 image full screen. (the 16:9 embedded in 4:3 is stretched horizontally to full screen, the vertical is still 16:9 embedded in 4:3.) 4:3 content is stretched. I never got that on the panny and am told that the SA 8300hd only puts out 4:3 on s-video and composite. (I tried the composite and I get the same behavior). So something in the chain is doing the stretching. I'm suspecting some EDID quirk between the TV and maggie. Cycling the aspect ratio settings on the maggie has no affect on anything, so I assume the TV is doing the stretching? I can get the behavior I expect, standard 4:3 with 16:9 embedded, when I set that HDMI input on the TV to an aspect ratio of 4:3. The only down side to that is that now OTA programming is also now all 4:3 with 16:9 embedded. I can't find one set of settings for all.
I have yet to record anything to disc to see what another player will do with the recorded content. If it is the TV that is doing the stretching, then I should get all 4:3 content to disc as I did with the panny, but for now that is just conjecture.
