Clear as mud. What did you use to recover it with ?
If you installed only Windows from scratch, your DVD drive may NOT be detected correctly until AFTER you have loaded the main chipset drivers for the mboard.
XP doesn't have the drivers built in for most things that first came out after XP was first released, circa 2001, and it doesn't have some of the drivers built in for things made before that.
Whenever you load Windows from a regular Windows CD (or DVD) from scratch, after Setup is finished you must load the drivers for the mboard, particularly the main chipset drivers, in order for Windows to have the proper drivers for and information about your mboard hardware, including it's AGP or PCI-E, ACPI, USB 2.0 if it has it, and hard drive controller support. If you have a generic system and have the CD that came with the mboard, all the necessary drivers are on it. If you load drivers from the web, brand name system builders and mboard makers often DO NOT have the main chipset drivers listed in the downloads for your model - in that case you must go to the maker of the main chipset's web site, get the drivers, and load them.
As already stated, vaguely, XP has no built in software codec that can play pre-recorded DVDs (or copies of those DVDs) that have encrypted software - e.g. movie DVDs.
A USB optical (CD or DVD) drive requires that you have it plugged into a USB port that can actually supply the full max spec 500 ma of current.
In the following, the same things that are required for external hard drives are required for external optical drives.

In addition to that info...
For some desktop mboards you can have problems when an external hard drive is plugged into one of a pair of USB ports on the back of the case that are connected to the same USB controller, if there is another device plugged into the other USB port for the pair, because the pair can't actually supply 500 ma per port - they can only supply 500 ma in total. Usually those pairs of ports are one above the other, not beside each other. If you have two devices plugged into such a pair of ports, try plugging one of them in elsewhere on the back of the computer.
For MANY laptop and netbook mboards similar applies. The built in USB ports often cannot actually supply 500ma per port - they supply 500 ma in total for two ports that are close to each other. In that case, the external drive should work fine if it's the ony thing plugged into the USB ports built into the laptop or netbook, or if you have more than two ports, the only thing plugged into two ports close to each other.
CD only drives cannot recognize DVD disks of any kind.
DVD drives cannot recognize blu-ray disks.
