I'm a newcomer to the study of Home Theater technology. One of the aspects that I find confusing is CONNECTIVITY. Between standard RG6 coax, S-Video, Component Video, Composite Video, DVI and HDMI...I'm not sure what is a preferable technology, when it is preferable or why. Another issue is interconnectivity. In a system where there are various components (DVD, DVR, VCR, Surround Sound Receiver, TV) are there issues with remaining consistent between the connections from one component to the other. These are probably very naive and basic questions but I would appreciate it if anyone could point me in the right direction. Thanks!
