Why is there a limit of 2 hours per disc?

Q: Why is there a limit of 2 hours per disc?

A: While it is possible to fit more than 2 hours of video on a DVD, we do not produce such discs because of quality degradation. In order to fit more data on a DVD-R more compression is required. MPEG2 compression used in DVDs is lossy: the more you compress the lower quality you get.
