Battery longevity

My setup is as follows:

Pioneer AVH-P4100DVD
2007 OEM battery
OEM amp
OEM sub
OEM speakers

My battery has not exhibited any signs of weakness and the last time I took it to the dealer for an oil change, they checked the battery and it was good.

My question is this; my new HU can play DVD's and I was wondering approximately how long I can watch a DVD with the car NOT running? I know this is a subjective question, but I was just wondering from a hypothetical point of view based on the power required to run the system.

I'm definitely not an electronics expert, but would adding a capacitor to my system give me additional time?

Advice appreciated!

it depends on volume. the most powerful device is amplifier and subwoofer. dvd monitor needs less. imho 3-4 hours for battery isn`t problem
Finally, adding a capacitor as a power buffer might reduce ignition noise, and may improve the dynamic response of the audio system; it won't extend run time. Capacitors are "lossy" (self-discharge). Adding one will decrease your run time.
you needn`t it. it`s choice for sound pressure competitions, when you need huge amount of energy for big "BOOM"
