Here is the result of my checking further:
1. The Apple key appears to have the same function as the Windows key and the Option key on the Mac which is also marked Alt appears to have the same function as the Alt key on the PC. For example, Contol Option(Alt) Delete on the Mac running XP brings up the Task Manager. Furthermore, pressing the Apple(Command) key on the Mac brings up the Start Menu in XP.

2. The volume control in the System Tray affects the sound volume corectly. The volume control buttons on the keyboard cause the slide bar on the System Tray volume control to move up and down having the appropriate control on sound volume.

3. The issue of sound card effects is unknow to me as I have a Mac-Mini with whatever sound card comes in it. If you have a more exotic sound card I do not know if it will work the same

4. Inserting a blank DVD-RW results in the normal Windows response under Computer>DVD-RW. Pressing the Eject key on the keyboard ejects the disk the same as under Mac OS

5. Inserting a TV compatible movie will play under Mac OS as delivered. However, Windows Media Player under XP will not play the same DVD unless you buy a compatible decoder on line that ranges in cost from $15-$30. I would opt just to use the Mac OS to play DVDs unless you have some other agenda.

That's all for now.

Cheers,
