1. will be able to use my DVD creator software to make DVDs on the DVD recorder/player?
MAYBE. Some software like Roxio only works with some USB DVDRW drives.
2. will my computer be able to "see" previously recorded DVDs played on the recorder/player,
You didn't reveal what recorded those DVDs. For example the DVDs I recorder on my Philips DVD recorder must be FINALIZED before they play on my PC. DVDs I made on my PC play fine since the software I used can play them.
3. will I be able to save those videos to my HD?
MAYBE. Copy video from DVDs is something that I've seen hundreds of discussions on and the answer DEPENDS on the details. The answer to this is "Maybe."

If I buy an External DVD player/recorder that has a USB port, and if I use that port to connect it to my Windows XP Pro computer, will the computer "see" the recorder player so that I will be able to use my DVD creator software to make DVDs on the DVD recorder/player? Also, will my computer be able to "see" previously recorded DVDs played on the recorder/player, and if so, will I be able to save those videos to my HD? Thanks!
