Here are some frames from the NTSC and PAL DVDs, and the Blu-Ray: http://imgur.com/a/nymHs

Notes:

  1. All were taken using VLC's built-in snapshot functionality for the best quality, with no deinterlacing, aspect correction, or any other video effects or postprocessing (except see #2, below). If you know of a better way, let me know.
  2. The Blu-Ray images were automatically converted by imgur from .png to .jpg. The remaining images, all .png, appear unchanged from what I uploaded, based on the file size.
  3. The PAL images show very noticeable lossy compression. I took them from the Region 2 Limited Edition DVD box set of season 1, ISBN 5030305891015, released in 2002. There's a more recent R2 DVD edition, maybe the quality is higher.
  4. The DVDs are ASIN B002GP7ZWI, released in 2009.
  5. The Blu-Rays are ASIN B00E688720, released in 2013.
  6. The NTSC DVDs show evidence of 3:2 pulldown. I chose frames without noticeable interlacing for this test.
  7. It's possible that the NTSC video was created directly from the PAL masters, in which case this experiment won't reveal any additional detail.
