How do I burn the movie to DVD using Movie Maker?

Movie Maker doesn't burn video DVDs directly. Instead it sees if you have Windows DVD Maker installed and will then offer you the "Burn to DVD" option. If you aren't seeing that option, then you must not have Windows DVD Maker.

Windows DVD Maker came with Windows Vista and Windows 7 but support was dropped after that. So if you are on Windows 8 or later, you will not have the option.

This is similar to what Apple did in dropping iDVD support back in 2011.

The video DVD format is a legacy format that came from the era of analog TVs and has a maximum vertical resolution of 480p (NTSC). It uses the older MPEG-2 codec to compress the video. I wouldn't recommend it as an archive format for your movies, but if you must absolutely have a video DVD to play in an older DVD player, then you'll have to look for 3rd party solutions like DVD Flick or DVD Styler, or similar.

If you have a Blu-ray player (or a game console that supports Blu-ray playback) then you should be able to use the .mp4 file that Movie Maker creates directly. You can just burn the .mp4 file directly onto a disc (even a DVD disc) as a data file (not in video DVD format) and it will play in a Blu-ray player.

Alternatively, many SmartTVs can playback the .mp4 file if you save it onto a USB stick. You can also try using streaming over your home network using DLNA. Or perhaps you can load it on YouTube and use casting to a Chromecast or similar device.

Plug the USB thumbdrive into your computer. It should show up as a new drive letter. Using Windows Explorer, copy from wherever you saved on your hard disk and paste the file onto the USB drive.

Alternatively, save your movie again and this time give the destination as the USB drive instead of your computer hard drive. This will take longer since it has to rerender the movie, so if you know where you saved it before, I'd use method #1.

Please advise how to put the movie  on a usb stick. Thanks for your help

Thank  you  so  much  for  your  help.  Could  you  please  let  me  know  if  the  movie  which  was  done  in  movie  maker  will  play  on  other  computers  or  do  I  have  to  do  something  to  it.  I  haven't  done  a  movie  for  about  6  years  back  then  I  put  them  on  dvd,  I  think  I  read  somewhere  it  isn't  as  good  as  usb.  I  have  another    movie  in  media  player  and  put  that  on  usb  but  it  won't  work  in  my  friends  computer.  Some  one  advised  I  could  share  on  drop  box..but  I  messed  that  up  too..ha  ha.   Do  you  think  I  should  go  with  the  dvd  or  try  usb   if  the  quality  is  better...I really  appreciate  your  help.
