Not a direct answer, but on the off chance this helps. I haven't tried S-Video input yet but can see why they might think that you would never (wrong in this case) want to do atimed recording through the S-Video.
I was told that the Input type setting should be to cable in the US. My 5006 would not find more than 3 to 6 channels. Happened with two units. Lite-On Customer Service said the IRC and HRC were European stabndards, not of use in the US. Went through two units before I bull-headedly tried the auto-setting using IRC and HRC. Turned out ComCast cable in my area north of Chicago matched the HRC setting and it worked perfect.
