Emm, "concurrent" recording may relax the problem,
because the CPU is too busy to be too fast :-)

(Assume -for example- that the CPU is too fast and
see a "ready" bit, that's acuttally still the old
one, because the AV71xx controls it by software and is
too slow to clear it in time. (It's just an example what can happen
with too fast CPUs and hardware. I don't know if this is
true for the DVB-S)
