Odd behaviour from LIRC /dev/input

Hi

I'm not actually sure of the source of my problem so I figured I'd list it under the primary symptomn: Lirc lags behind in remote button input by one. I'm aware that's very legible so here's a handy table:

Code:

 _____________________________________
| What I press: | What LIRC spits out:|
|_______________|_____________________|
| Up            | [Nothing]           |
| Down          | Up                  |
| Down          | Down                |
| Menu          | Down                |
| Subtitle      | Menu                |
| Exit          | Subtitle            |
| OK            | Exit                |
|           etc...                    |

Anyway like I said I don't know where this error is stemming from, I doubt it's actually from LIRC though, as catting /dev/input/event7 (my IR input) into xxd yeilds similar, though substantially less legible, behaviour.

Now LIRC is not using any special drivers, just its dev/input one, so it's probably a problem with Linux's input system, the card's drivers, the card itself, or the remote. (The card is a Compro T300 DVB tuner, with a simple IR reciever plugged into a jack at the back; it's based on the saa7134 chipset.)

Anyway has anyone seen this behaviour before, not necessarily with a remote but any input/event device? And more importantly is there any way to fix it?

I'm an ex-Ubuntu-noob who recently switched over to Fedora 8 x86_64, so keeping things simple would be highly appreciated.

Thanks,
