This is not really the thread to discuss those topics, however, yes it's WS and no for DD5.1, since the audio connections are analogue audio.
Be aware that component video connections are pretty rare on DVD recorders (limited to more costly ones) and we're mostly discussing composite, S-video and RF-coax. If this is indeed CGMS-A, then that may not affect component video connections on DVD recorders for example (I just don't know since the topic comes up so rarely).
It'd be good to get some feedback from someone using any of the three SD analogue connections.
