DDV 7000 : How much recording time will a 512MB memory card

[want2learn]

Hi

I am thinking about buying a Digilife DDV 7000 or Aiptek DV2 , I am told that the DDV7000 can take a max 512MB memory card ? & give me about 2hrs 20 mins recording time ? another guy tells me I will get approx 14 min recording time out of a 512MB memory card? so can anyone verify & confirm the actual recording time from a 512MB memory card( DDV7000)

ALSO CAN ANYONE RECOMMEND WHICH IS THE BEST DIGITAL VIDEO CAMERA

Digilife DDV7000 or the Aiptek DV2

Thanks
