The lossy compression strategies used in DVRs make them only suitable 
for moving picture for direct human consumption. They do things like 
only encoding the differences between frames, encoding the movement of 
blocks, transmitting a rough update to a frame and then refining it over 
successive frames if it doesn't change, and selective control of spacial 
frequency response.

Because the compression is 3D (two in space and one in time), sync 
pulses are even more important to them.
