[This is a double post btw, stop doing that.]

first off, I hope you know you need 2 receivers to watch one thing & record something different. (please refer to page 11 of the operating instructions of your DMR-E75V).

2nd of all, that recorder doesn't support HD inputs, so I guess you would want to run S-Video into it & component out of it.

You'll probably want the component from your set top box going into your AV receiver & another component coming from the recorder (for when you want to watch playback) & use your AV receiver to switch between component sources. & then connect the settop box to the recorder with s-video. If you understood this correctly... yes... you would have 2 video outputs coming from the settop box, one that bypasses the recorder (the component cable) & one that goes to it (the s-video).
