PAL-M is incompatible with 625-line based versions of PAL, because its frame rate, scan line, colour subcarrier and sound carrier specifications are different. It will therefore usually give a rolling and/or squashed monochrome picture with no sound on a native European PAL television, as do NTSC signals. PAL-M details: [11] [9] [10]
Some DVD players (usually lesser known brands) include an internal transcoder and the signal can be output in NTSC-M, with some video quality loss due to the standard conversion from a 625/50 PAL DVD to the NTSC-M 525/60 output format. A few DVD players sold in Argentina, Paraguay and Uruguay also allow a signal output of NTSC-M, PAL, or PAL-N.
[4] [5] [6] It is one of three major color formats for analog television, the others being PAL and SECAM. NTSC color is usually associated with the System M; this combination is sometimes called NTSC II. [7] [8] The only other broadcast television system to use NTSC color was the System J. Brazil used System M with PAL color.
Analog television systems were standardized by the International Telecommunication Union (ITU) in 1961, [1] with each system designated by a letter (A-N) in combination with the color standard used (NTSC, PAL or SECAM) - for example PAL-B, NTSC-M, etc.). These analog systems for TV broadcasting dominated until the 2000s.

CCIR System M, [1] [2] [3] sometimes called 525–line, NTSC, NTSC-M, or CCIR-M, [4] [5] is the analog broadcast television system approved by the FCC (upon recommendation by the National Television System Committee - NTSC) [6] for use in the United States since July 1, 1941, [7] [8] replacing the 441-line TV system introduced in 1938.

PAL: PAL M color subcarrier: 3.579545 NTSC: NTSC M color subcarrier; see colorburst. More specifically, 5 * 7 * 9 / 88 = 3.579 54 MHz. Because these are very common and inexpensive they are used in many other applications, for example DTMF generators 3.582056 PAL: PAL-N color subcarrier 3.595295 NTSC: NTSC M color subcarrier, plus horizontal ...
Perhaps the most technically challenging conversion to make is the PAL and SÉCAM to NTSC conversion. PAL and SÉCAM use 625 lines at 50 fields/s or 25 frames/s; NTSC uses 525 lines at 59.94 fields/s (60000/1001) or 30 frames/s; The NTSC standard is temporally and spatially incompatible with both PAL and SÉCAM.
Not all of the possible combinations exist. NTSC is only used with system M, even though there were experiments with NTSC-A in the UK and NTSC-N (625 line) in part of South America. PAL is used with a variety of 625-line standards (B, G, D, K, I, N) but also with the North American 525-line standard, accordingly named PAL-M. Likewise, SECAM is ...
