When reinstalling Mac OS X, what does that mean? Is it checking the DVD for errors, or the HDD for errors?
15 inch MacBook Pro 2.16 GHz, 2 GB RAM, 7200 RPM 100GB HDD.

Dual 2.5 GHz Power Mac G5, 1 GB RAM, 250 GB HDD, ATI Radeon X800XT.

It's checking the hard drive for errors. I would wait for it to finish, because several times I've gotten errors while checking, so it saved me from going through the whole install to find out.

No, in Panther, it also has a step that checks the installer disc. When it says "checking the installation disc", it's checking the disc with the installer on it. Then, once that's over, it runs Disk First Aid on the disk it's being installed onto, and fixes any problems.

I never saw disk first aid run (and I've reinstalled OS X a few times). All I see is it go straight from "Checking your installation disc" to the preparing the packages for install. Is it safe to skip the "checking the installation disc" and save ~40 minutes from the install?

As long as you're confident that your install discs are OK, you can skip it. I've seen people with dodgy discs (which Apple happily replaced) skip this, and end up with a decidedly non-working system because the install aborts halfway through.

Best to let it run through the check at least the first time, the rest of the times, well it's up to you I guess.

I have a slightly used PB 17 1.5 and every time the install gets to Checking Your Installation Disk it freezes, whether at 10 or 60 percent, etc. I know the DVD Restore disks for 10.3.3 are good as were used on another PB 12 without trouble.

If skip this I get an install ok. Should I be worried? Is this a SuperDRive problem, or worse?

Once installed I can install from teh drive and watch movies, no problem.

Thanks.

You won't see Disk First Aid run from within the installer. It's running in the background during the checking disks step.
