Bryan,

Wow! That was the secret! I had been playing with the res.ini, but to no
luck. I thought POV couldn't render right, as it stretched the image. I had
tried the different resolutions (mentioned on Wiki-P), but to no avail. I
had thought the problem was my understanding of HD. The "right (16/9)" is
the key. Thanks!
