A variant of the above, using the USB vendor/product id worked but I also found
this:

KERNEL=="event*",ATTRS{phys}=="usb-0000:03:00.1-1/ir0",SYMLINK+="input/ira"
KERNEL=="event*",ATTRS{phys}=="usb-0000:03:00.3-1/ir0",SYMLINK+="input/irb"

and now t I have this:
$ ls -l /dev/input
---8<---
crw-r----- 1 root root 13, 76 Jun 10 09:54 event12
crw-r----- 1 root root 13, 77 Jun 10 09:54 event13
---8<---
lrwxrwxrwx 1 root root      7 Jun 10 09:54 ira -> event12
lrwxrwxrwx 1 root root      7 Jun 10 09:54 irb -> event13

I haven't yet been able to get that (or several variants of it) to work.

Apparently Mythbuntu uses a simplified variant of lirc called inputlirc. This is 
configured using /etc/default/inputlirc .

I found some instructions here:
<http://wiki.xbmc.org/index.php?title=HOW-TO:Configure_VRC-1100_remote_for_Ubuntu>

Using this:

$ more /etc/default/inputlirc
# Options to be passed to inputlirc.
#EVENTS="/dev/input/event*"
EVENTS="/dev/input/ira"
OPTIONS="-g -c -m0"

my remote now generates keypresses, and I now think I just need to map them to 
mythtv using ~/.lirc/mythtv.

To configure this I haven't had to specify anything at all about my specific 
remote, in fact I removed lirc, so I guessed that a driver was already doing it, 
which seems to be confirmed by the source for one of the modules that my dvb 
card uses.

around line 1291:

This is the keymap for the TeVii remote that I have:

static struct rc_map_table rc_map_tevii_table[] = {
	{ 0xf80a, KEY_POWER },
	{ 0xf80c, KEY_MUTE },
	{ 0xf811, KEY_1 },
	...

Assuming that I can the mythtv key bindings set up then I should have a working 
remote. <rant>That is one of the most painful Linux config experiences I have 
had for several years. Mainly because the documentation that I could find seems 
to be outdated, and I still didn't find anything that would have pointed me in 
the right direction straight away.</rant>

The next thing I'd like to set up is the ability to use another remote. The wife 
likes the one that belonged to our Philips DVR that died. I read somewhere that 
I should be able to use them both at the same time but I'm not sure what 
documentation to trust. Any ideas?
