I don't have a DVD recorder, so I'm jumping in cold here...

What I'm hearing is that you can't erase an hour of a crappy
basketball game and replace it with a CSI re-run, right?

You would have to format the entire DVD and start over?

Ummmm, if you are talking about a stand-alone DVD recorder box, then the
answer is yes.

On a computer you can burn a DVD "multisession" so that if you had leftover
space you could use that space later.

If they make a DVD recorder that can do multisession, I haven't seen it.
That function would best be DISABLED on stand-alone consumer boxes anyway.
Otherwise, the only player you could use the disk on would have to be one
that is in a personal computer. What good is that?

But this isn't a big deal. DVD +/-RW media can be "burnt" something like a
thousand times, and I think I paid like a buck a piece for my last pack of
10, which I thought was expensive, at the time.

I've had some disks that have been recorded every week or two and are about
18 months old now, still going strong.

So if you have to erase the entire disk and start over, who cares?
