Although I planned to buy an external DVD burner when I purchased my WinXP
netbook in 2009, I didn't do it. Now I have more of a need for one
(installing some software, copying files, playing CDs and DVDs) and have
found an enormous number to choose from.

The advice I received here in 2009 was to check reviews and not to go by
price--that more expensive wasn't necessarily better. But what else should I
consider? For example, will all burners work with WinXP? Is tray loading
better than slot loading? Should any brands be avoided? I'd be grateful for
advice.

Thank you!
