And what's better? Recording into a HD miniDV tape or an HDD or a memory card? Whats the difference?
And my Laptop only accepts firewire? I dunnow much about that either...
miniDV tape is probably the highest quality in the consumer range. You must capture the video in sequential fashion (you have to play the video and capture it at the same speed it was recorded). I've been doing it that way for years. It doesn't bother me much, but sometimes I wish I didn't have to do it. One huge advantage of tape, in my opinion, is archival storage. I never overwrite tapes, so I can always go back and fetch video clips that I've erased or lost.
HDD and memory card are similar in the way they work except that a memory card takes less power (longer battery life) and an HDD probably has more capacity (more recording time for the same quality). Both of them allow non-sequential or random access, so you can copy clips from them simply by dragging and dropping the clips onto your hard drive in any order you want. You just have to wait for the transfer, which is generally faster capturing from tape.
In the consumer world, all video formats are squeezed using specific formulas that have names, like MPEG-2, AVCHD (
Wiki definition). Your computer software must be able to understand the specific method of squeezing in order to return your movie to an editable state. I believe most editing suites now support the more common compression. If you stick with Rik's list (that was an excellent list, Rik ... I don't know how you keep up with all of these consumer cams), you'll be in the mainstream formats, so you need not worry too much. If you purchase some off-the-wall consumer camera that uses some secret squeezing formula, it's possible you'll be stuck using their software to convert everything ... if you can even get it off the camera.
Stick with Canon, Sony, JVC or Pansonic and you should be just fine. I can't speak for E-bay; it works when it works, but you must be careful. There is a used department at many of the large camera resellers and they will stand behind what they sell.
