1- How many hours of video in SP mode can a camera record with a 30GB HD?

2 - Are there any pro's or cons as far as recording to a camera's hard drive, over a camera with a Mini DVD Drive like I have currently?

3 - What's the longest battery life out there, and does the HD recording give you an extended battery life over DVD recording? My current one barley lasts the required 30 minutes when recording to DVD disk..

4 - There are a few HD Cameras in the $800 range, and with a tax return coming up, it's within affordability. Is there much of a reason to go Hi-Def with cam-corders, or could you get 1024X768 picture quality on a non hi-def camera?

And 5 - How many record in True widescreen format?

Thanks
