Does the unit switch automatically from HD component to SD S-video or composite?
Robert with Value Electronics says it does. However, Feldon23 in a response on a different thread said that you must go into the set-up each time to switch from Component to S-Video/Composite. This has been gone over in many other threads.. TiVoPony (works for TiVo) says that when you select 480i it will output S-Video, Composite, and then either Component or HDMI based on your menu selection.
