This is likely why earlier DVDs from the 90s look better. The extras, elaborate menus, and commentaries take up space that can otherwise be used for video quality. By the end of the golden era for DVDs, those things got out of control. Saving space for video bitrate was the concept behind the Superbit DVDs.
Superbit discs can be read by all regular DVD video players, but their film files were encoded at a bit rate that is, according to Sony, approximately 1.5 times as high (6-7 Mbit/s vs 4-5 Mbit/s) as that of standard DVDs, which helps minimize artifacts caused by video compression and allow the image to be pre-filtered less prior to compression, which results in more detail. Superbit should not be confused with either Blu-ray or HD DVD discs, both of which are different media formats of much higher bit rate and resolution, and are incompatible with standard DVD video players.
To maximize space for the main feature, static menus are used and commentary tracks are removed.
