XVCD or XSVCD with same bitrate and resolution, which one?

[Reinder]

When making a XVCD or XSVCD I can choose to have the same bitrate and resolution. I know XSVCD has other benefits but in terms of quality of the movie: does using Mpeg1 or Mpeg2 make a difference in quality when having the same bitrate and resolution? Or does it depend on which resolution you are going to encode to?

Everything else being the same, the quality should be the same. However, consider this, at a 480 x 480 resolution (I'm talking video only at the moment) and 2520kbits/sec video bitrate or less, mpeg-1 you would be making an XVCD, mpeg-2 you would be entirely within the SVCD specification, which would probably be compatable with more DVD players than that XVCD.

Video bitrate, resolution and a few other factors all interact together to produce the perceived quality (or lack thereof) of a video.
