Problem with IS1U60 receiver

[JOANCABRER <JOA...@te...>]

Hi all. 
I've made the circuit in lirc's homepage with an IS1U60 device, but It
doesn't work. When I run mode2 to test it, I get too many lines, and
irrecord doesn't work too. 
I would like to know if somebody has tried lirc with this device, and if
I have to change or add anything to the circuit to make it work. I hope
you'll be able to help me. 
Thank you
