PV951 - LIRC doesn't work

[Petr S. <pst...@so...>]

Hi,

I have a ProVideo 951 with a remote control, Linux 2.4.18, LIRC 0.6.5. I
have the proper PV951 config file installed but the LIRC doesn't seem to
work (irw doesn't output anything etc). When I run irrecord I get the
following messages:

Hold down an arbitrary button.
irrecord: decoding failed for all remotes
irrecord: decoding failed for all remotes
1 x 2100553 [2100553,2100553]
.irrecord: decoding failed for all remotes
1 x 2100553 [2100553,2100553]

the output is different each time even if I keep pressing the same key
on the RC and definitely looks like a random garbage. Eventually it
quits with

irrecord: gap not found, can=B4t continue

I looked into /var/log/messages and found this message:

The RC works perfectly under Windows so it should not be a hardware
problem.

Thanks for any hint.
