Okay, new info, and much of what I have said is in error. maybe I should close this thread and start a new one
First, jjeff, I took the cover off, and there is almost nothing to see. The HDD is on one side, the DVD drive on the other. In the center is a big metal cover which does not look like a heatsync. There is a circuit board under these components, but all I can see is jumber wires and a few capacitors. It looks pretty darn simple for such a complex piece of equipment! The power module is just behind the DVD drive, and that has a few more components, but no chips are visible unless I get more agressive with further dissassembly. It is really unlikely at this point.
I tossed in a CD, and the Gracenote thing found lots of info each song. I guess that bit works just fine. I think it's unlikely I will put hours on my DVD drive laser listening to CDs though.
I tested the SCART connectors, and both top and bottom connectors put out a video signal. The adapter I have has video in and out, but I haven't had the chance to test the inputs. Since the outputs work, I have no reason to believe the inputs won't. My adapter does not have S-Video connections.
Here is the embarrassing bit
. Almost everything I said earlier was in error to some extent. I was very rushed because as soon as the wife saw the disks would play, she wanted to watch them wich ended my testing (yeah, blame the wife, like that'll work!).
To those who said the Vizio was PAL capable, thumbs up. I wanted to test it so I hooked it all up and changed the EH-68 to PAL from the menu. The Vizio displayed it fine, either mode. I then put in the PAL disk and played it. It didn't matter what mode the EH68 was set to, the Vizio displayed the picture. Video, S-Video, HDMI, PAL or NTSC, the Vizio worked perfectly. It DOES have a display to show the input signal type, and here is where I made my earlier mistake. When in NTSC mode, if I put in a PAL disk and play it, the EH-68 switches to a 576i signal while the disk is playing. As soon as I press stop, it reverts to 480i.
So, the player does NOT convert PAL to NTSC. It's just that the TV I was using for testing was much more flexable than I thought, or than the manual stated. When I connected this to my PT-53WX53, the menus and other screens displayed just fine, and that was my second mistake. I never played the disk! When I pressed play, the picture became unwatchable, pressed stop, and it was okay again. I added the PAL to NTSC converter I bought and the display stayed solid. The picture through the converter is really not very good on my 53 inch television, but it's serviceable. When text is shown on screen it is the most noticeably bad, but when it is not showing text, it's okay. Not great, but okay.
