[mythtv-users] hd converter box lircd.conf problems ==

[Sam Bruner]

The formatting might have been different because I get an archive message instead of each individual message.  This makes responding a little more difficult.  

I have two separate devices for ir receiver and ir transmitter.  I got both from http://www.irblaster.info/

I got the dual head blaster.  My intent was to use this for my dish box and the dtv box.

I do not see errors in the syslog.  Like I said it will transmit for my dish box.  How can I determine the modulation frequency of the dtv box receiver?  I have read that this is tricking.

I am getting rather frustrated.  I would like to simply use a digital card but I do not have the power to decode the digital files.  

How do I increase the debug messages of licrd?  ie debug level 5?

If irw responds to all keys, you have LIRC config that is at least
good enough for the receiver you are testing it against. You didn't
state what type of receiver/transmitter you are using though, as some
may not be able to transmit the full range of protocols supports by
LIRC; or whether you ran irrecord in raw mode or against a protocol
header file. If you are using serial receiver/transmitter, you should
be OK as these are extremely flexible in what they can send and
receive.

Once you have loaded the modules for your IR transmitter, you need to
test irsend with the lircd.conf file you created and the LIRC device
for the transmitter. You should check your syslog for any errors
during this. You need to place the transmitter very close to the STB
in order for the IR transmissions to be detected. If you look at the
transmitter whilst it is sending through a digital or video camera,
you may be able to see the IR pulses.

Many remotes tend to use the 38kHz carrier frequency, but there are
other popular frequencies, particularly located between 36-40kHz and
50-56kHz.

Finally, your email client appears to have messed up attributions,
indenting and lost the message threading information...
