Why didn't the mechanic change ALL of the bearings? A full rebuild kit with all the bearings and seals you need is only about £150-180. Can't understand why a mechanic would want go through all that labour charges and not change them...
If the whining changes pitch with engine revs in any gear, it's definitely an input shaft bearing. The fact the noise goes away when you press the clutch pedal when stationary would strongly suggest this.
If the whining changes pitch with road speed, then it's on the final drive (output shaft) end.
Another possible, but rare, is not enough oil in the gearbox.

A moments silence please, for our brothers in the NAD-zone.
