A VHS recorder does not record NTSC, PAL, OR SECAM. Color processing is used before the recording. The same is true of V2000.
Perhaps I should have been clearer: Has anyone ever used a DIRECT-recording SECAM recorder? That's what broadcasters had to use -- and COULD, in NTSC and PAL.

Has anyone ever used a SECAM recorder?Hi Mark, I've used some sparingly, i never owned one personally, but my parents do (i personnaly only started to record video after the advent of the digital area). There were hot discussions on some french forums regarding the way SECAM was (mis) treated in the VHS format (with a simple division by 4 of the FM chroma frequency). As an alternative recording format, MESECAM can be used. I never set my expectations very high for VHS, so with that preconception, i would say it does the job even in SECAM, especially when starting from a good source (analog satellite SECAM broadcasts), and viewed on a relatively small screen (55 cm). My parents never rented films so i cannot judge how SECAM fared in the area of recorded movies. I must admit i never had a critical look on this as i was not very interested in this format. I once (1986) recorded a film (from a terrestrial TV broadcast) onto a V2000 VCR (i remember it was Polanski's "Dance of the vampires") and was pleasantly surprised by the result, even though V2000 is supposed to have a smaller bandwidth than VHS. But then again, it was not on a very big screen. It is not clear VHS problems can really be tied to the video standard in itself. I am also thinking that, in formats like SVHS, it would have been possible to do better with SECAM: S video separates luma and chroma, but still transmits two chroma components simutaneously, which means you need to modulate them somehow on a carrier. With SECAM, you only need to transmit one component at any given moment, so you could do away with some modulation/demodulation steps and gain in quality . I doubt this was ever done, though. Also, there should be ways to take advantage of the fact that SECAM chroma is already in FM format, which is better suited to tape. This is unlikely to happen now, anyway :-) ---------------------------------------------------------------------- You can UNSUBSCRIBE from the OpenDTV list in two ways: - Using the UNSUBSCRIBE command in your user configuration settings at FreeLists.org - By sending a message to: opendtv-request@xxxxxxxxxxxxx with the word unsubscribe in the subject line.
