120 minutes of typical "DVD" video. The DVD Video standard calls for a maximum PEAK bitrate of about 10Mbit/s

As for WHY 120minutes is deemed the average with a variable bit-rate I don't know. Perhaps just a throwback to legacy magnetic tape formats?

Wiki Quote:

Typically, data rate for DVD movies range from 3 Mbit/s to 9.5 Mbit/s, and the bit rate is usually adaptive. It was first available for retail around 1997.

So, 5 is not all that far of for an average?
