The format on which you have written the file is not read on the DVD player and so when the files is burned please choose the option to write the files in the format which can play on any player mode when the request for burning comes up.

Is your DVD drive a Combo DVD ROM and CD Read/writer? If so it cannot burn DVD only reads DVDs and read and burn CDs.
If the program cannot find a DVD burner then either the burning software cannot support that model DVD burner ot the DVD burner is faulty.
To test the DVD burner, remove it and install it into another computer to test the burner to see if is faulty.

When you formated you erased the driver you need to use your dvd writer as a dvd writer and player. If your dvd-rom came with a cd use it to reinstall the driver and program it uses. Otherwise you can search for your driver thru the manufacturer website or go to www.driversguide.com and find it there.

On the back of a CD-writer or a DVD-writer is a small grid (2 rows) of gold pins.

Each vertical set of pins is labelled: MA(ster), SL(ave), and C(able)S(elect).
Be sure that one drive has a small jumper between the MA pins,
and the other drive has a small jumper between the SL pins.

Was there any software on CD-ROM that came with the DVD-writer,
e.g., software to play DVDs, and software to write CDs and DVDs?
To "play" a DVD, you'll need that software.
To "play" a music CD, Windows Media Player will suffice.

1st step; Acquire/buy a cd/dvd rom drive cleaning tool kit from your local pc store.
2nd step; Install a dvd coder/decoder software, try Power DVD player software it has a trial version
3rd step; After installing the DVD coder/decoder from Power DVD player try playing a dvd movie rom disc it should work/play... hope these tips help ;-)

Use the net to download driver. Then you can try using your drive. Otherwise your drive may have gone defective itself not allowing windows to see it.

Open your sound controls to make sure nothing is muted or set on low volume.
If that's not the case, open your audio drivers program and check to see if nothing is muted.

No but it sounds like your burner is DOA. Take it back and exchange it.

If you have posted the correct model of writer, then it only supports the writing of DVD+R and DVD+RW discs, but CD-R and CD-RW disc writing are supported, and it should play all forms of DVD, so it won't burn DVD-R and RW discs, but if it wont play all types then try a cd/dvd cleaner, but to be honest when writers start playing up the lens is normally faulting and a replacement drive will be required.
