I noticed you did, but that was never in dispute (at least on my part)
so no proof was necessary. :)

Good for you. I was curious about the North American situation since
I've only ever seen Europeans, Australians, etc. discussing wide screen
signaling. I was beginning to think that perhaps a similar concept
doesn't exist in 525/60 countries, or it isn't standardized between
products from different manufacturers, or doesn't work over analog
signal paths, or isn't available on the SD sets. Or any combination of
those things.
Then again, the whole 16:9/DTV/HDTV transition has been handled in a
somewhat different way in the US and in Europe. Here, all these
transitions - from 4:3 to 16:9, from analog to digital, from SD to HD -
have been somewhat disconnected from each other, and the transition from
4:3 to 16:9 came first. (People have been buying analog SD 16:9 sets
since about 1995 or 1996 - generally long before they even knew that the
transition to DTV is coming - and 4:3 sets have also supported 16:9
switching for an equally long time. [Before they disappeared from the
stores, that is.])

I think you mean NTSC. :) Connecting the DVD player using a composite
video cable could make for an interesting test. Does the automatic
aspect ratio switching still work that way?
