What is invalid format in dvd operation?

Ransom-ware? Just a guess really. Try running spybot and see if it detects anything.

Is it licensed DVD or it was burned?

You only format a CD/RW or a DVD/RW, which are re-writeable.

Regular discs do not need to be formatted (CD-R or DVD+R, DVD-R, DVD+R DL, etc.).

To format the DVD/RW idisc, use the "burner" software ( Sonic?, Nero?) and choose [Tools] [Erase Disc] (erase is the same as format)

You Could:

1) Check that your DVD reader is working (use another disk).
2) Check the region code for the disk (most likely reason).
3) Take it to the shop you brought it from.

Basic Information:

i) try to choose  right burner for eg: Nero CD/DVD Burner

ii) try to choose the right format,

     for eg: MP3/MP4/ Audio Songs will come under Audio format
               in such case select "Audio CD/DVD format" in Nero CD/DVD Burner


     for eg: .DAT/MPEG/MP4/Video will come under Video format

                in such case select "Video CD/DVD format" in Nero CD/DVD Burner


     for eg: "DATA CD format" is only storing some data on CD/DVD iresspective whether it is                            Videofile or Audio file, 

                these "DATA CD formated" CD/DVD when played in DVD Player will play only Audio files 
                but no Video Files 

   
   

now a day, no installation CD or DVD come with any of the new laptop anymore. you need to make a backup copy of the operating system when you first fired it up. if yu did. you still can make a backup from programs>accessories>backup.
but since the laptop is DOA. look for your receipt, the laptop should have one year warranty from best-buy. if not it should be have the warrant from DELL.
since you don't have the DVD. you can request one from DELL.

Ran into the same problem with this DVD player and my LG tv. Try this:
Open the DVD tray, with the DVD tray open press the HDMI select button until the proper resolution for your tv is illuminated, put the DVD back in, close the tray and try again. Simple fix -- worked beautifully for me.

Good luck
