Melody, Burning video can be a little tricky if you want it to 'autoplay' (start to play when the disc is inserted).

So, let's see if you actually burned anything to the disc:

• Put the disc in the DVD+-RW/CD drive.
• Click on your Start button
• On the right side, you should see a choice for 'My Computer' - click that
• Now you should see icons for the drives you have on your computer. One will have a picture of a DVD with the a name below it something like: 'DVD-RAM' - Double-Click that.
• That should open Windows Explorer - do you see any icons in it, or is it blank.
• If you see an icon, double-click that and see if your video starts to play.

Let me know what happens, and I can try to guide you from there.

One other note:
It doesn't look like your Audiovox will be capable of playing a DVD or CD created on your computer. If it could you would see either +/-R following it's name. You might try looking for a basic DVD player that you can leave at her house. Now that BluRay has hit the shelves, the price of a basic DVD player has really come down. We just purchased one for $49 at SamsClub, and it plays all formats, including +/-R.
