Most likely they are SVCD, or even VCD, movies daisy-chained onto a DVD.
While some of these SVCD transcodes can be of excellent quality, they are by no means DVD quality and use a correspondingly lower bitrate (less than 2.5 Mbits/sec), together with a smaller frame size (480 x 576 in the case of PAL).
All this makes for smaller files - hence the ability to fit several movies on one DVD disc.
