Sounds like worn-out synchro's to me - But check your oil level first.

"Manual transmissions in modern passenger cars use synchronizer rings to eliminate the need for double-clutching. A synchro's purpose is to allow the collar and the gear to make frictional contact before the dog teeth make contact. This lets the collar and the gear synchronize their speeds before the teeth need to engage. " Take from the HOWSTUFFWORKS.COM site

I was trying to get some of their diagrams...other stuff about gearboxs.

Hope it helps.

CYA.

Its your syncro. Im sure that at lower speeds where the gear shafts are not spinning as fast you can get it in the gear fine. Crack that case open and change those bad boys out.
