I have been using WinXP a long time and I have a problem yet to be solved until now. It is UDF format DVD cannot be read in WinXP whereas it can be read perfectly in Win98/WinMe. I don't know why this will happen and how to solve it. Expert here can help me?

Not specifically an XP problem.

UDF format is a format put on a CD when it is used a big floppy. When you install a program like InCD or Direct CD, the UDF reader is installed automatically. But if you want to read those CD's (or DVD, in your case) on another machine, the UDF reader has to be installed on that machine and every other machine you want to be able to read the CD's in UDF format.

If you look in the help section of the programs mentioned above, you will find this to be true, although not in as plain language. Poking around in the installation CD, should turn up a folder containing the UDF reader installation program or I think you can download it.

If you are trying to read a UDF DVD on the same machine that burned it and you can't, then you need to see if there is an upgraded version of the program.

I thought XP had support to read all UDF file systems. I think a lot has to do with what version UDF the OS supports. As I understand it there was 1.02 which is for DVD-ROMs, then 1.5 for CD-Rs and CD-RWs, and I think 2.01 is needed for DVD-RAM.

Windows XP Professional reads UDF versions 1.02, 1.50, 2.0, and 2.01 on CD, CD-R, CD-RW, DVD, DVD-RAM, and magneto-optical discs. Support is implemented in the Udfs.sys driver. If you have a DVD-RAM drive, you can use Windows XP Professional to format DVD-RAM discs by using FAT32. Windows XP Professional does not include built-in support for formatting DVD-RAM discs by using NTFS, although some third-party tools might enable this capability.
And for Windows 2000 http://www.microsoft.com/technet/tre...t3/proch17.asp

The Universal Disk Format (UDF) is new for Windows 2000. UDF is a file system defined by the Optical Storage Technology Association (OSTA).

Note Windows 2000 reads both UDF versions 1.02 and 1.50. Windows 2000 does not support writing to UDF volumes.

Boy, am I out of date. Sorry.

Sounds as though the UDF writer that you used to burn the DVD's in Win9x isn't compatible with the native UDF reader in XP.

Maybe if you told us what burning software you used, it would help others to avaoid the situation. Or hit google with the info.

actually I have no idea also. Those DVD cannot be read is I got from my friend and WinXP description for the disc is UDF format DVD. And WinXP can detect it is 7GB DVD but when you browse for the content, all the file is 0KB.
