I've narrowed down this problem to one of the ioctls that freevo sets
during start up causing a DMA crash in the firmware encoder with
ivtv-0.4.7. Already posted a message to the ivtv list.
My next task is to figure out which ioctl is causing this problem. And
will try ivtv-0.4.6 as this is a version that doesn't include the latest
DMA changes to the driver.
