Yes, I read the other thread that was referenced and saw that others 
were suffering the same or similar symptoms, and agree that it would 
seem unlikely to be the hardware. But I would still not rule it out.

But consider this - all of us using lirc are using pretty much the same 
exact lirc software.  (OK, maybe some have slightly newer versions than 
others) Even if you consider the different combinations of kernels and 
distros we all use with lirc, I would submit that the differences in 
lirc software among us are smaller than the differences in the hardware 
that we all use with lirc.  In this set of software combinations, we 
have a relative handful of users reporting intermittent problems, as per 
the aforementioned thread.

On the hardware side, you have not just the remotes, but different 
commercially made IR receivers, serial or USB, and all the different 
homebrew lirc receivers.  Even if you just consider the seemingly common 
homebrew lirc-serial receiver listed at lirc.org, there are many 
different combos of resistors, ICs, capacitors, soldering and assembly 
skills, etc. used in constructing these.  No two will be exactly the 
same.  (OK - almost no two.)  This larger combination of possibilities 
to me represents a more likely source of a problem.  It seems like one 
possible explanation for intermittent operation could be a bad solder 
joint, or overheating voltage regulator, or other flaky hardware component.

I hope I don't come off as preachy - I'd just hate to see you go down 
one road and not consider the other path.  Besides, the sooner you can 
get rid of this pesky problem, the sooner you can start enjoying your 
mythtv, right?
