your system seems to block itself, so lirc does not get enough
cpu timeslots to decode properly, and since the interupt umasking seems to
help, i would try to renice the processes using top, to give lircd a big 
negative value and all vdr processes a high positive value.

b.t.w. which chipset do you use ?
for me a switch from an i810 to a via kt133a based board (from celeron 900 
to amd 1100), solved a lot of strange timing errors (lircd: IEEE your clock 
jumped backwards..) and IDE CD/DVD trouble (could not read cdrw or dvd-r).
my system load is 5-8% for dvd and ~3 for vcd, i use gcc 2.95.3, a glibc 2.2 
system and a 2.4.2x kernel.

i think it might be your (pci) hardware timing and or the kernel/libc timing
(do you use glibc 2.3, or 2.6 kernel, or gentoo ?)
