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

I guess where I was going with this is that I might have 1 hour of
programming that I want to save and another hour that I want to delete
on the same DVD. Say I recorded CSI and then Without a Trace on the
same DVD. Later I want to delete Without a Trace and add another
episode of CSI, just to keep things organized.

I'm sensing that this can't be done, right?

(This is all hypothetical - I'm just trying to understand the
technology)

Each time you record something (like CSI and WaT in your example), you
create a new "session". When recording something new to a disc, you have
two, and only two, choices (so far as I know, unless there's some
*really* fancy software or recorders out there):

1. Overwrite all existing sessions (essentially "erasing" them, although
they may not need to be physically erased).

2. Add a new session to the existing ones.

So no, you can't choose to keep some sessions and delete others.
