This sounds to me like it is lirc that is inducing the stutter. 
resolving this may be as simple as increasing the "niceness" (do a 
"man renice" for more info) of the lirc processes. But if you do 
this, you may cause some transmissions to fail, because the CPU 
switches away from lirc at times when it should be blasting the next 
bit of data.

Other options that may help:

- upgrade your kernel to one that supports the HPET_TIMER option

- get a blaster like either of these, which would offload the 
CPU-intensive stuff: http://www.mytvstore.com/product_id_004.html

- get a faster CPU
