How do I finalize a disk (CD-R and DVD+/-R) using Windows ?

Hi:

How do I "finalize" a disk (CD-R and DVD+/-R) using Windows ?

I want to finalize the disk...not just close the session/disk.

From what I have read in Windows Help, "closing" allows me to write to the disk later.

Is this true, if the disk is just R, not RW ?

I have burned JPEG images (.jpg files) to CD-R and DVD+R disks.

When I try to play them in my Sony CD/DVD player, it won't recognize the disks.

Sony's user manual says that the disks must be "finalized", not just "closed".

How do I do that with Windows ?

I treid finalizing these disks with Roxio Creator Basic, but it doesn't do anything, except eject the disks.

Windows still says that the disks have free space, and the DVD player can't recognize them.

From what I understand, if the disk is finalized, the will show no free space available.  Is this correct ?

Note:  The disks work correctly on my HP laptop which uses Vista 32-bit Home Premium.  I can view the JPEG images.

Thank you...
