can anyone tell me if all dvd`s are interlaced or not? i want to encode as close to the original dvd as possible. what is the difference between the two (interlace/non interlace)? i burned a dvd and the original dvd was progressive (non interlaced); i had the source set to interlaced and the output set to interlaced, well to make a long story short; the burned dvd played choppy. the audio was ok, the video was choppy. i using tmpgenc plus v2.59 (paid for). any ideas?
