1. The easiest way is buy a region free DVD player, many modern DVD players will play and convert both NTSC and PAL DVDs and will also play DVDs that may have specific regional encoding, helping to avoid the regional problems created by the different formats and specifications.

2. IFOedit is the best conversion software. IFOEdit allows users to parse VOB files, remove and add video/audio/subtitle streams to VOBs, create new IFO files, create DVD images and burn DVD-Rs. (A VOB file is a container format contained in DVD-Video media.)

3. Another way is using DVDSanta that is an all-in-One software that helps you copy, convert and create DVD movies. It can convert video files (include DVD videos) into DVD format. DVDSanta's results are not very good but it does work.

4. A program called ConvertXtoDVD converts your movie files to a compatible DVD playable on any home DVD player but you won’t get the menu's.

Converting PAL video to NTSC involves adding extra frames into the footage and this can result in slight judders during fast movement scenes when done by most basic home editing software (Linear Interpolation). However by using Inter-Field Interpolation or Adaptive Motion Interpolation techniques, the inserted frames are averaged from the frames before and after the point where they are inserted and result in much smoother playback.

PAL (Phase Alternating Line)
NTSC (National Television System Committee)
SECAM (Séquentiel Couleur à Mémoire—Sequential Color with Memory)

Each standard is incompatible with the other two. Also, the equipment that demodulates the signal must be formatted for that signal.

Generally NTSC is used in North America, most of the countries in South America and Japan. PAL is the format for the UK and most European countries except France and parts of Eastern Europe which use SECAM. For example, a recording made in the France could not be played on an American VCR.

If you view video tapes that are from outside of the United States, or send videos abroad, you must first convert the tape to or from the foreign television standard.

This table illustrates the differences between the video standards:

NTSC-J looks slightly better than ordinary NTSC because it has a better signal/noise ratio ordinary NTSC which uses 3.58 MHz as its subcarrier).

Although NTSC 4.43 uses PAL's color subcarrier frequency of 4.433618 mHz, the chroma is still encoded as an NTSC signal. Thus although it uses PAL's subcarrier, tapes recorded in NTSC 4.43 will not display on a standard PAL monitor or play in a standard PAL VCR.

The NTSC 4.43 system, while not a broadcast format, appears most often as a playback function of PAL cassette format VCRs, beginning with the Sony 3/4″ U-Matic format and then following onto Betamax and VHS format machines. As Hollywood has the claim of providing the most cassette software (movies and television series) for VCRs for the world's viewers, and as not all cassette releases were made available in PAL formats, a means of playing NTSC format cassettes was highly desired.

The output of the VCR when playing an NTSC cassette in NTSC 4.43 mode is 525 lines/29.97 frames per second with PAL compatible heterodyned color. The multi-standard receiver is already set to support the NTSC H & V frequencies; it just needs to do so while receiving PAL color.

The existence of those multi-standard receivers was probably part of the need for region coding of DVDs. As the color signals are component on disc for all display formats almost no changes would be required for PAL DVD players to play NTSC (525/29.97) discs as long as the display was frame-rate compatible.

1. The scanning beam scanning every other horizontal line, from the top of the image to the bottom, which equals one field.
2. The beam completes one line at 15,734.27 Hz. That's 15,734.27 cycles per second! This is the horizontal scan rate.
3. The beam shuts off at the end of the first field.
4. Back at the top, the beam fills in the other half of the lines- the even numbered lines.
5. Two fields are scanned for every frame.
6. The two fields are displayed in immediate succession, creating the appearance of a single 525-line frame.
7. The beam scans all the lines in a frame at 59.94 Hz. This is a vertical scan rate of almost 60 cycles per second. This rate was chosen because it is compatible with the alternating current (AC) electricity supply of 60 cycles per second found in those regions where NTSC is used.
8. Color, for NTSC video, is carried at 3.58 MHz.
9. Sound, for NTSC video, is carried at 4.5 MHz.
