Another reason is that is quite cumbersome on the viewer side. The switching between "angles" is usually rather slow and to watch another angle you have to rewind. Yes it eats space, but the maximum DVD bitrate is of no concern as each angle has it's own max bit rate (the angles are on the disc placed after each other and the player skips over the angles not played).
If the angle features, in stead, were added as extra's on a disc would use the same disc space (and often more easy to navigate).
Yes and no - whilst it is indeed true that swapping angles will dump you backwards (in exactly the same way switching audio streams on a DVDA will also dump you back to the start of the track), there are issues with bitrate - using multi-angle reduces your maximum available bitrate as detailed below.
- 5 angles or fewer: 8 Mbps maximum for the track’s combined bit rate
- 6–8 angles: 7.5 Mbps maximum for the track’s combined bit rate
- 9 angles: 7 Mbps maximum for the track’s combined bit rate
