Most likely something is wrong with the bandwidth setting for the line.

If you are using a Cisco, at the IOS prompt, "show int" will show you
the bandwidth in the output, something like this:

Serial5/0 is administratively down, line protocol is down
  Hardware is M8T-V.35
  MTU 1500 bytes, BW 2048 Kbit, DLY 20000 usec, rely 255/255, load 1/255

The "BW" is the bandwidth setting, and this is what MRTG will retrieve
via the SNMP ifSpeed variable and use as the basis for the calculation.
I suspect this is currently set to something other than 64Kbit. 
(Though I do not know why MRTG should apparently be using an
inconsistent value for the in and the out directions.)
