A friend's new hi definition TV, I think he said it's a dlp, has
pretty serious distortion. Where the image kind of waves as the
picture pans, with most distortion at the edges. He asked the store
where he bought it about this and was told that it was because he
needs to get hi definition service from his cable or satellite
provider; that the distortion comes from the hi def tv compensating
for the lack of hi def signal and will not work properly without
that.

Any truth to this?

Thanks.
