I just made another recording and I will compared them side-by-side. My first recording was from the 20th when it was not listed on the online calendar as HDTV and from last night when it was.
All I can say is that the the version from the 20th (I have not yet checked last night's version) had a huge band on the bottom of the frame (about 5-10 pixels) and most of the still frames lacked details.
I record, and sometimes keep upconverts, if they look really good. Finding Nemo comes to mind. That upconvert was very very very good and I can't wait to compare it to the 720p version from ABC.
The 20th version of NT was very good. It looks good-to-very-good on the 106" screen. But some of the close-ups of people's faces lacked that punch that HDTV transfers have.
Can it be a BAD HD transfer??? Could be. But do we rather have a bad HD transfer or a real good upconvert.
I will give you my honest opinion once I get the version from last night through the frame checker.
