David Tindale, from Australia, sent me the following technique:
Here is my work-around to get an analogue video signal from a Macbook
Pro to an SD TV.
First you need to purchase a Mini DVI to VGA
adaptor ($45 approx.
in Australia), then you need an AV to VGA Digital
Scan Converter Box (anywhere from $30 to $70
Aus.). The Converter box comes with an RCA cable, a VGA cable, a
USB power cable and the converter box itself.
It's fairly straight-forward to connect:
- Plug Mini DVI into Computer, connect VGA cable to Mini DVI adaptor.
- Connect other end of VGA cable to Converter Box, plug RCA cable
from Converter box to TV.
- Connect USB power cable to Converter box and computer and Bob’s

The real problem solving came with getting the Macbook and TV to
see each other. The solution that worked for me is as follows:

Select System Preferences > Displays

Set resolution to the same as the TV (for me this turned out to be
720 X 480 stretched). (In the US, it would probably be 720 x 480. LJ)

Go to ARRANGEMENT and make sure Mirror Displays checkbox is selected
In FCP go to VIEW drop down menu and set EXTERNAL VIDEO to ALL
FRAMES. I was then able to playback full screen and check
color correction.
There are a couple of problems with this workaround, one is that
you’re
working in a very low resolution with FCP so I don’t recommend
editing, this is just for viewing and checking.
Another is, when resetting the resolution to go back to editing, make
sure you have UNCHECKED the Mirror Displays checkbox BEFORE resetting
resolution.
I made the mistake of resetting resolution first and my computer
freaked out, it flashed through a number of resolutions before settling
on a black screen that I couldn’t get out of. I ended up having
to reboot my computer (this is a trap for young players)
I hope this will help anyone else who has had the same problem as
me of having to work with SD as well as HD footage. All-in-all the
fix cost me about $70 including postage.
