These are generally caused by another device stealing the IRQ from the
tuner card, and this is likely to cause corruption in your MPEG stream. 
To find out what devices the card is sharing an interrupt with, `cat
/proc/interrupts`.  Shuffle the card around until it's not sharing any
more, or
until it's sharing with a device that has sensible interrupt handling.
