True, but it's not necessarily the only way.  As a previous poster said, 
this is not necessarily a common function and perhaps doesn't need to be 
high performance.  Many people might be perfectly happy to pay the CPU 
cost to seek backwards to the previous keyframe and then seek forward to 
the exact frame. 

This way seeking backwards might incur a small delay, and forwards would 
be instant, but at least we now have the option to do it...

Consider the main uses, for example checking whether that ball really 
went in the goal - you just want to flick forwards and backwards over a 
couple of frames and it really wouldn't matter if it took even a few 
seconds to seek backwards, it would just be useful to be able to do it...
