Powering a 5V and a 9V circuit from one 9V battery -- isolation help?

For size/weight reasons, I'm hoping to use a single 9V battery plus
mic2950 5V regulator to power a mini video camera (9V) and some RC
servos (5V). Unfortunately, every time the servos move, there's a burst
of interference on the video signal. There's no interference when the
camera and the servos are powered by separate batteries.
The circuit is simple: 9V battery, mic2950, camera, and RC stuff, just
wired together the obvious way. I tried adding a capacitor between
output and ground of the regulator, but that didn't have any effect.
Is there any way to eliminate the interference?
Or, is there a 5 or 6V power source that's smaller than 4AA cells, or
an alternate 9V battery that's smaller than the usual?
Thanks for your attention.
Michael
