The JVC HM-DH30000 vcr provides 2 types of output resolutions from HD tapes:
1) Full resolution (HD), which I haven't seen yet and
2) reduced resolution ('SD'=standard definition).
I believe the reason for this is copy protection: The MPAA does not want any high resolution output from sources (e.g., a vcr) that would allow a high quality copy to be made. If the component output of JVC were full bandwidth, then (in theory) the signal could be used to drive an MPEG encoder to create a quality digital copy. Future generation VCR's will only provide a very high speed digital output which will drive displays with digital input.
If an HD tape doesn't contain the proper code, the JVC will only playback in standard definition (SD). I get a brief message on start-up that says the tape is playing in high speed mode (HS) AND standard definition (SD). I understand tapes made in Japan (JP tapes) playback in full resolution. Apparently the machine can be tricked into playing unapproved tapes (e.g., tapes recorded with PV-HD1000 vcr's) in full resolution by first playing a JP tape, then inserting the desired tape into the machine. If the vcr is stopped during playback, then process must be repeated. If anybody knows of a better way to get full resolution output, please tell us.
