I'm in the process of getting a canon hv20. I know almost nothing about videoing and even less about editing.

1) What's a good editing program for a newbie?

I'm not sure I'll be trying to record in HD in the beginning since I don't own a HD tv. (not yet.. not yet... )

My computer is probably a bit weak for this too. It's a HP with with a pentium 4, 3.00GHz. .99 GB of RAM (.99?) I think it has 193 GB of free disk space. (windows XPmedia center edition)

2) Should I buy an extra hard drive?

3) Do I need a whole new computer?

Thanks!
