Switching Video (VGA & TV composite) ?

I am wanting to dynamically switch the prop outputs to/from VGA & TV (composite).
My analog is not up to scratch, so I just wanted to check here (Phil are you there???).
I thought I would switch the prop pins (before the resistors and connectors) via a Quad 2:1 Mux (or Quad SPDT switch). I have two parts in mind. Both have 300MHz BW and ~10 ohm resistance and should hadle the current.
They are... NX5DV330PW (5V part) http://www.nxp.com/documents/data_sheet/NX5DV330.pdf
and TS3A5018DBQ (3V3 part) http://focus.ti.com/lit/ds/symlink/ts3a5018.pdf
No doubt the same could be used to switch in a replacement digital signal as well.
