WINDOWS XP DOESN'T SUPPORT UDF DVD ROM MULTI LAYER

Hello there,
I recently created a DVDROM title formatted with UDF which is a dual layer format(8.4 Gb). Soon after the disc is manufactured I tested and found that Windows 2000, Windows XP and Winn Nt 4.0 doesn't read them fully. Windows 98 and Macintosh can read the contents fully. Windows 2k and XP can display half the data only. Microsoft has accepted that there is a bug in their OS which is later than win 98 and will have the patch in their next service pack. My question is has anyone got any answer for this or a fix for this issue.

I appriciate your responses...Thanks

Don't forget to backup your previous udfs.sys file before replacing it.
>>i think dan misunderstood your question.
I believe I understood the question.  It is not unusual for a manufacture-specific driver to fix a problem that is found in a Microsoft-generic driver or even in the underlying system.  Without details from surnswam, we might never know.

DanRollins: There is a few third-party UDF drivers. Most DVD-RAM drives are completed with'em. But DVD-RAM drive's manufacturers do not develop UDF drivers itself.
Have you tried installing Windows XP SP1. Some problems I experienced with DVD's were resolved after installing Windows XP SP1.

For a list of fixes in Windows XP SP1, visit the following URL:

http://support.microsoft.com/default.aspx?scid=/support/ServicePacks/Windows/XP/SP1FixList.asp

You can download Windows XP SP1 here:

http://www.microsoft.com/windowsxp/pro/downloads/servicepacks/sp1/sp1lang.asp

No, SP1, as described in http://www.microsoft.com/windowsxp/pro/downloads/servicepacks/sp1/sp1lang.asp includes another patch for udfs.sys which solves some copyright problems while playing "Seven Dwarves" and "Snow White" Disney's movies, but doesn't solve a problem of double-sided DVD-RAM disks. You may still order the patch by phone (refer to http://support.microsoft.com/default.aspx?scid=kb;en-us;329112) or wait for official SP2.
you are correct, msa. and this is explained in the knowledge base article i provided above.
Yes, unfortunually Micrisoft still didn't realized a stable and bug free version of udfs.sys. Like anything from Microsoft >:(
No comment has been added lately, so it's time to clean up this TA.
I will leave a recommendation in the Cleanup topic area that this question is:

Split between DanRollins, night_monkey and msa2003
