Answers.Text: Ah, sorry, I missed that your display is physically 4:3, then of course, there will be black bars. But on a widescreen display, a DVD can display uncropped with no bars.

Body: <p>I have videos with ~5000 kbps of avg. bitrate, if I burn the videos to a PAL DVD, which the resolution is low...(720x576), with 1000 avg. bitrate, will it be obvious to see the difference in quality? If so, can you suggest how much bitrate do I need in a dvd video? I prefer better quality and lower in size. Since the ratio of PAL DVD is 1.25, but the videos' ratio is 1.7 (originally 1080p), will the side being cropped or shrinked until it fit the width? (First time trying :D) <br><br>

  More than 'what do I need', you should ask yourself 'how much am I allowed'.
  
  [This page](https://en.wikipedia.org/wiki/DVD-Video) mentions an average bitrate of 4-5 Mbits/s, this is audio + video + subtitles. It also depends on the length of your content (as you also have a maximum capacity of about 4.7 Gb for a single layer DVD-Video).
  
  FLAC is not supported on DVD-Video, common audio codecs are MPEG1-L2 and ac3.

  I would take a page from Amazon and say that you should limit bitrate to 6.5 Mbps for audio and video combined but make full use of that ceiling, as much as the 4.7 GB single-layer DVD size allows.
  
  ## Audio
  
  The allowed codecs are MP2, Dolby AC-3 and PCM. I'd recommend MP2 with a bitrate between 192 to 256 kbps for stereo audio.
  
  ## Video
  
  Codec is MPEG-2. A couple of things to note: the picture isn't composed of square pixels, so the displayed picture ratio isn't 1.25; it will be 1.33 (4:3).
  
  And it is possible to present an uncropped widescreen (16:9) picture without letterboxing. How to do so, depends on the software you are using to convert and/or author the DVD. But basically, when converting you ought to set the display aspect ratio to 16:9.
