shit rana somebody ate your dinner or are you finally eating some of the crap you have been posting here lately cant make heads or tail what you ranting about you may sound intelligent about interlace or progressive techniques maybe you should try to understand this first
"There are basically two ways to display video: interlaced scan or progressive scan. Progressive scan, used in computer monitors and digital televisions, displays all the horizontal lines of a picture at one time as a single frame. Interlaced scan, used in standard television formats (NTSC, PAL, and SECAM), displays only half of the horizontal lines at a time (the first field, containing the odd-numbered lines, is displayed, followed by the second field, containing the even-numbered lines). Interlacing relies on phosphor persistence of the TV tube to blend the fields together over a fraction of a second into a seemingly single picture. The advantage of interlaced video is that a high refresh rate (50 or 60 Hz) can be achieved with only half the bandwidth. The disadvantage is that the horizontal resolution is essentially cut in half, and the video is often filtered to avoid flicker (interfield twitter) and other artifacts.
It may help to understand the difference by considering how the source images are captured. A film camera captures full frames in intervals that are 1/24th of a second long, whereas a video camera alternately scans fields of odd and even lines in 1/60th of a second intervals, resulting in interlaced frames that are 1/30th of a second long. (Unlike projected film, where the entire frame is shown in an instant, many progressive-scan displays trace a series of lines from top to bottom, but the end result is about the same.)
DVD is specifically designed to be displayed on interlaced-scan displays, which represent 99.9 percent of the more than one billion TVs worldwide. However, most DVD content comes from film, which is inherently progressive. To make film content work in interlaced form, the video from each film frame is split into two video fields —240 lines in one field, and 240 lines in the other— and encoded as separate fields in the MPEG-2 stream. A complication is that film runs at 24 frames per second, whereas TV runs at 30 frames (60 fields) per second for NTSC, or 25 frames (50 fields) per second for PAL and SECAM. For PAL/SECAM display, the simple solution is to show the film frames at 25 per second, which is a 4 percent speed increase, and to speed up the audio to match. For NTSC display, the solution is to spread 24 frames across 60 fields by alternating the display of the first film frame for 2 video fields and the next film frame for 3 video fields. This is called 2-3 pulldown. The sequence works as shown below, where A through D represent film frames; A1, A2, B1, and so on represent the separation of each film frame into two video fields; and 1 through 5 represent the final video frames."
also saw your discription on gold media on a different post in case you dont know what you discribe are hybrid dvds and not gold to make it easier for you true gold disc can be detected from the inner ring which is all gold hybrids are clear and to make it much easier hold the disc at an angle and if any other hue besides gold can be seen then it is a hybrid
disc rot is not limited to silver disc only an other of your misconception other factors contibutes it also climate, glue coming apart between the layers and oh yes the dvd case themselves contributes to this through insertion on the inner ring this is why BEI are using ringless cases only if they were not so cheap and would go for the gold 
forget the above excerpt obtained from dvd faq go to their web page for the full story and everything you want to know about dvd and were too proud to ask :p

I did not buy a DVD player to watch sub-VHS, VHS-like, or barely better-than-VHS quality transfers, and I certainly am not the only one here who feels that way. I will not give my money to the likes of Yash Raj, Eros, and Video Sound. For most movies, I would rather not watch them at all than to experience it in a manner that does not even approach acceptable, and if, by some chance, I do want to watch a Baba or YRF DVD, I will rent or borrow it.
