Try playing the DVD on your computer, just to ensure that it did indeed burn as a 16:9 video (which I'm sure it did).
If it did, you'll need to find the setting on your DVD player (and all DVD players have it) for forcing your TV to display widescreen. Usually DVDs trigger this automatically -- but sometimes home-burned DVDs don't.
Larry,Please tell if it worked.
And, the setting on one's TV (especially later models) can also impact how things are displayed. So many possible settings...
When you say that the edges don't show, are you talking about the left and right edges, or is it the bands on the top and bottom that aren't showing?
Thanks, yes! I played it on my computer, and it came out fine; then did some serious messing around with the menu on my DVD player, and found the setting that allowed it to display the video correctly - that is, in "letter box" format.
