Hi to all,
Thanks! to Vol.2 for the LA7673 pinout.
Isolation transformer: anyone who works with modern electronics needs one.
All modern gear use SMPS (Switch Mode Power Supplies) which equates with HOT chassis.
Iso-Tx's are often found for cheap at vintage radio/Ham swap meets or contact a local radio club, often old-timers give away items as they thin out/dispose of collections.

Video in mod: i would stick with Composite Video. Component or RGB is a whole other ball game.
Opto-isolator: i suggest you build this design, it works and has very good video bandwidth, 17MHz at -3dB.
