I'm using a photo transistor, not a IR receiver like TSOP4838, so I guess my troubles could come from this.
Difinetly. It is not about accuracy, but about modulation. IR signals are modulated by a frequency between usually 32 and 56 kHz, 36-38 kHz being most common. TSOP receivers have a demodulated output that only gives a signal if such a modulated IR signal is received. This modulation is used to mask out ambient light that could otherwise give a signal, making reception impossible. This demodulation should be done in the analog part of a receiver circuit, it would be almost useless to implement that in the µC.
