2004 manual Mazda 3 won't go in gear. Please help me to know where to start. Troubleshooting methods etc. Thank you.

Can you see that pressing the clutch pedal correctly moves the slave cylinder and release fork (at the front of the transmission)? You've tried all gears, including reverse (when the engine is running, of course)?
