I used to have a lot of missed channel changes and recordings on my
Dish 311, too, but I finally solved it. I used to get about 90%
accuracy, but now I get a perfect 100% of signals sent properly. I
can't tell you 'exactly' how I solved it, but it was a combination of
kernel config, lircd.conf and my channel change script. I'm using
lirc-0.8.0 and this IR blaster: http://iguanaworks.net/ir/. I don't
know exactly what in the kernel helped if anything, but I made a lot
of changes to preemption, timing and other cpu stuff. I didn't use
nice at all. Here's my config files, in case this will help anyone.
