It's a week down the road, and a several consultations and phone calls with a Microsoft engineer later, but -- for some -- there is some good news, at long last, RE:
DLA after SP2.
There is also some BAD news and a few warnings.
First, the GOOD News
For IBM users, at least.
Here are the steps by which I eventually got DLA working again with SP2:
Caution: Before following these steps make sure that you have the original versions of DLA and RecordNow software available to you for reinstallation!
Also, make sure that you download from Lenovo/IBM's web site, their fixes for Veritas versions of the DLA and RecordNow software that shipped with their machines. These updates will upgrade and convert your software from the Veritas variety to Sonic's variety. The URL below will get you to the site where the DLA upgrade is found. Note the restrictions on drives, etc.

The next site will get you to the RecordNow update, which, again, converts your version from Veritas to Sonic.

My recommendation is that you order a CD-ROM version of SP2 from Microsoft. It is absolutely free to registered users of SP1a. It makes what follows easier; but, it's not necessary if you've got it saved somewhere on disc or HDD.
1) Uninstall SP2, uninstall Veritas DLA, and uninstall Veritas RecordNow (The Veritas version of DLA which shipped with my Thinkpad last year was ver 3.26).
2. Boot to SAFE mode, re-install SP2, and then restart.
3. In normal mode, reinstall the Veritas version which originally shipped with your IBM computer. Do not attempt to use this version, and do not insert a DLA disc into the computer yet. The upgrade to Sonic ver 4.95 is just that: an upgrade. It will not install a standalone version, but will only upgrade a previously installed version.
4. Run the DLA upgrade to version 4.95 which you downloaded earlier.
-------
At this point you should be able to regain control of your DLA discs, and you should have the ability to read from the older UDF version and write to them without crashing or getting error notices from XP SP2.
-------
5. Reinstall the original version of RecordNow.
6. Run the update which you downloaded from IBM/Lenovo. It will delete the old version and rename folders, etc, and install RecordNow! (with an exclamation point as part of the new Sonic name).
-------
After taking these steps in this order, my Thinkpad will now do DLA as it always has in the past, without SP2 barking at it, issuing error messages, to crashing into the Blue (Screen Death).
You will need to reinstall any Windows Updates or Security Patches which you may have installed after applying SP2 the first time.

The BAD News from Sonic
Warning: If you are running a previous (Veritas or other) version of DLA and have been having problems after installing SP2, I recommend that you
DO NOT pay for and download the version of DLA offered by Sonic on their website (
www.sonic.com), not if you want to be able to read from AND write to your old DLA discs. Their version (which I paid 19.99 for, downloaded and installed yesterday) is version 4.90. It will work OK under W2K if you are running that. It will
NOT work OK under XP SP2.
Here's what it does. It
will permit you to read your old DLA discs without the annoying error messages issued by SP2 ("ADC" and "XP cannot read this disc"). It is stable under SP2 and does not crash it. But it will
not permit you to write to your old DLA discs.
If (and this is a big
IF) you are willing to copy all the data from your old DLA discs to another drive, reformat each disc with Sonic's version of DLA, and then restore the data to each disc, then the Sonic ver 4.90 will,
eventually, provide you with a workable DLA solution and access to all your old data.
If you are like me and have many DLA discs which you use for ongoing projects, this process simply takes too much time to be feasible. At 22+ minutes of reformat time each, and approximately 7 minutes of copy time on the upload to HDD (for a full disc) and approx. 11 minutes of download back to the disc, in a best case scenario you are looking at more than 40 minutes per disc to re-do your archives -- and that is just for CDRW archives. DVD-RW archives may take much longer.
--------
Bottom Line:
--------
IBM's version 4.95 update takes care of the problem for those users who had IBM systems running the previous version of DLA. Those of us fortunate enough to have had Veritas software can upgrade and enjoy DLA life after SP2.
Perhaps other users could try the IBM fix to see if it will work for them.
I don't know.
Good Luck!
