Question about Televison & Video
When DVD stop. Press P.scan it will ask Interlaced -> Progressive -> Progressive. U just press the Interlaced. Then it will become normal to play it. And u also Check NTSC/Pal mode to set changes. Check out.
A. How Traditional Video is Displayed
Normal video, such as from VHS VCRS, Camcorders, and television broadcasts, is displayed on your TV as a result of scanning series of lines on a screen surface in a format called interlaced scan. In this system, lines of video are displayed in an alternate fashion on a television screen. All the odd lines are scanned first, then all the even lines. These are referred to as fields. This process results in an interlaced image. Each frame on your screen is made up of the two interlaced fields of video. Although video frames are displayed every 30th of a second, the viewer, at any given point in time is only seeing half the image. Since the scanning process is so quick, the viewer's brain perceives the video image on the screen as a complete image.
The Difference Between Progressive Scan and Interlaced Scan
Progressive scan differs from interlaced scan in that the image is displayed on a screen by scanning each line (or row of pixels) in a sequential order rather than an alternate order, as is done with interlaced scan.
In other words, in progressive scan, the image lines (or pixel rows) are scanned in numerical order (1,2,3) down the screen from top to bottom, instead of in an alternate order (lines or rows 1,3,5, etc... followed by lines or rows 2,4,6). By progressively scanning the image onto a screen every 60th of a second rather than "interlacing" alternate lines every 30th of a second, a smoother, more detailed, image can be produced on the screen that is perfectly suited for viewing fine details, such as text, and is also less susceptible to interlace flicker.
Video is another issue which continues to present most problems. Current players typically output analog video only, both composite video on an RCA jack, as well as S-Video in the standard connector. However neither of these connectors were intended to be used for progressive video, so yet another set of connectors has started to appear, to carry a form of component video, which keeps the three components of the video, one luminance signal and two color difference signal, as stored on the DVD itself, on fully separate wires (whereas S-Video uses two wires, uniting and degrading the two color signals, and composite only one, uniting and degrading all three signals). The connectors are further confused by using a number of different physical connectors on different player models, RCA or BNC, as well as using VGA cables in a non-standard way (VGA is normally analog RGB—a different, incompatible form of component video). Even worse, there are often two sets of component outputs, one carrying interlaced video, and the other progressive.
In Europe (but not most other PAL areas), SCART connectors are typically used, which can carry composite, Y/C (S-Video) and/or analog RGB interlaced video signals (RGB can be progressive, but not all DVD players and displays support this mode), as well as analog two-channel sound on a single convenient multiwire cable. The analog RGB component signal offers video quality which is superior to S-Video and identical to YPbPr component video. However, analog RGB and S-Video signals can not be carried simultaneously, due to each using the same pins for different uses, and displays often must be manually configured as to the input signal, since no switching mode exists for S-Video. (A switching mode does exist to indicate whether composite or RGB is being used.) Some DVD players and set-top boxes offer YPbPr component video signals over the wires in the SCART connector intended for RGB, though this violates the official specification and manual configuration is again necessary. (Hypothetically, unlike RGB component, YPbPr component signals and S-Video Y/C signals could both be sent over the wire simultaneously, since they share the luminance (Y) component.)

Push stop on remote to stop a DVD from playing. Push and hold stop for 5 seconds. If this doesn't work, try unplugging it for 5 minutes to reset it, let me know if neither options work and we can try a few other things.
