I downloaded a British TV show in HDTV and it was in PAL. Using Nero
to burn to DVD it barked at me and said the content is in PAL and I
have it set to burn to NTSC. I told it to burn to NTSC since that is
all my DVD player will play.
When I played it, the image quality was perfect. There was some slight
rasterization (?) but overall it was 90% there. I remember back during
the VHS era there was this "flickering" effect on converted tapes
thanks to the 25fps versus 30 (29.997)fps we use.
My question is, why doesn't this happen on DVDs? Did things advance so
far that that can extrapolate the missing data when going from 25 to
30fps?
How'd they do that?
