Julian...sorry for using a broad stroke, but SECAM and PAL are both 25fps, both 525 lines/50 fields, both horizontal frequency of 15.625kHz, both vertical frequency of 50 Hz, both video bandwidth of 5.0MHz, and sound carrier of 5.5MHz. the difference being PAL has a color subcarrier of 4.433618 MHz. thank you for response though and being in "PAL land" you should know.
