The location of the lircd socket has changed from /dev/lircd to 
/var/run/lirc/lircd. Therefore, the liblirc_client library used by most 
applications will look for /var/run/lirc/lircd. However, irserver 
creates /dev/lircd. Therefore, applications using liblirc_client won't 
find the lircd socket.

Because MythTV allows you to configure the location of the lircd socket, 
MythTV works.

If you are compiling irserver yourself, then you should patch it so that 
the LIRCD #define is /var/run/lirc/lircd rather than /dev/lircd. If you 
you are using a binary package, then you should ask the package 
maintainer to fix it.

Once you change irserver, you will need to change the MythTV lircd 
socket location setting so that it points to the new location.
