I haven't used this particular one, but i've used the dvp3u, the 7 and the 9. They all shot good quality video but the stills were awful, and totally unuseable. The cameras were indestructible and i still have the 9 with an ikelite housing as a backup. The other thing that bothered me with these cameras and ikelite housings was that they were too light for my liking. i struggled to keep them steady! Also, JVC makes great high capacity batteries as long as they fit in your housing! Finally, i just check out this camera at BH, and saw that it's a 2mp so i think video quality will be better than the ones i've used!
Hope this helps.
