I'm not sure what the point is to anamorphically enhancing letterboxed video from a laserdisc, which is a 400 line format for 4:3 displays. Unless the DVD creator has a scaler that is far superior to the one built into my TV(1), it's just going to look like any other non-anamorphic laserdisc capture blown up to fit the screen. In fact, some of the DVD's bitrate is going to be eaten up encoding the larger picture area, which takes away potential space for alternate audio tracks, extras, etc.

(1) And I readily concede this may be the case....
