I haven't used a TV Drive before, so I could be wrong, but it sounds like the box is disabling the TV scart because you are using HDMI. Presumably the reasoning being that if you are watching a HDMI output, you won't want the lower-quality RGB output. It may also be that the box uses some of the same hardware to drive both sockets, and as HDMI is encrypted, anything attached to an RGB scart wouldn't work.
One thing confuses me though. I can understand why you would need the DVD-R, but why use the Tivo?
