You do need the DB-23 for the video. The last time I checked Javanco in Nashville, Tn had them(although I heard a rumor they went out of business), Astro Too in Melbourne, Fl had them, and Skycraft in Orlando, Fl had them.

with any VCR or tv with video inputs, and you could probably
find someone that will pay you to take their A520 off
their hands.
