MESECAM stands for Middle Eastern Secam. MESECAM is not a broadcast standard. It is a VCR “standard” by which the color under process in VCR's is done by subcarrier shift instead of by frequency division. This means that an original Secam recording (frequency division) does not play back in a MESECAM player.
MESECAM uses an AM subcarrier and SECAM uses FM subcarrier. When MESECAM records a color signal onto VHS or Betamax video tape, the luminance signal is recorded in its original form (albeit with some reduction of bandwidth) but the chrominance signal of about 4.4 MHz is too sensitive to small changes in frequency caused by inevitable small variations in tape speed to be recorded directly. Instead, it is first down converted to the lower frequency of 630 kHz, and the complex nature of the PAL sub carrier means that the down conversion must be done via a superhet mixer to ensure that information is not lost....

Yes!!! There are some ways you can use to convert from PAL to NTSC or vice versa.
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....

Multisystem PAL support makes reference to the manufactured PAL television receivers that can decode all PAL systems except, in some cases, PAL-M and PAL-N. Many of them can also receive Eastern European and Middle Eastern SECAM, though rarely French broadcast SECAM. They will correctly display plain CVBS or S-video SECAM signals. Many can also accept baseband NTSC-M, such as from a VCR or game console, though not usually broadcast NTSC. Many sets also support NTSC with a 4.43 MHz subcarrier.
Many newer Video Cassette recorders and DVD players sold in Europe can play back NTSC tapes/discs. When operating in this mode most of them do not output a true (625/25) PAL signal but rather a hybrid of PAL and NTSC known as “PAL 60″ (or “pseudo PAL”) with “60″ standing for 60 Hz, instead of 50 Hz. Some video game consoles also output a signal in this mode. Most newer television sets can display such a signal correctly but some will only do so (if at all) in black and white and/or with flickering/foldover at the bottom of the picture, or picture rolling (it can be noted, however, that many analogue-era TV sets can receive the picture by means of adjusting the V-Hold and V-Height knobs â€” assuming they have them). Very few TV tuner cards or video capture cards will support this mode (a small number can, although software/driver modification is usually required and the manufacturers’ specs are usually unclear). A “PAL 60″ signal is similar to an NTSC (525/30) signal but with a PAL chrominance subcarrier at 4.43 MHz (instead of 3.58) and with the PAL-specific phase alternation of the red colour difference signal between the lines....
If you are having problems with your Xbox 360 using Pal 60 games, your TV may not be capable of displaying a picture at 60hz. PAL is a European standard that is meant to display at 50hz, 25 interlaced frames per second. The North American system is NTSC and it displays at 60hz.
The ADVCs only support standard NTSC (3.58) and standard PAL. Formats like NTSC 4.43 are not supported. PAL 60 is a non-standard format, which makes it hard to capture. Some capture cards with a certain Brooktree chipset are able to capture it in combination with Dscaler....

PAL-60 is NTSC with the chroma part converted to PAL (both encoding and subcarrier frequency, 4.43 MHz). PAL-60 or “pseudo PAL” standing for 60 Hz, instead of 50 Hz. The PAL colour system, either baseband or with any RF system, with the normal 4.43 MHz subcarrier unlike PAL-M, can also be applied to an NTSC-like 525-line (480i) picture to form what is often known as “PAL-60″, sometimes “PAL-60/525″ or “Pseudo PAL”. This non-standard signal is a cheap method used in European domestic VCRs and DVD players for playback of NTSC material on PAL televisions. It's not identical to PAL-M and incompatible with it, because the colour subcarrier is at a different frequency; it’ll therefore display in monochrome on PAL-M and NTSC television sets.
Majority of PAL games offered 50 and 60 Hz modes with no slowdown. Current generation PAL consoles such as the Xbox 360 and Wii also feature system-wide 60 Hz support....
