I had the exact same problem, and Steve is correct, the hard drive can't
write the buffer to the hard drive fast enough.

I solved the problem by doubling the buffer on the HD-3000 card in the
MythTv Setup. Under capture cards, select the HD-3000 and then go into
advanced. There are 2 settings set to 8xxx. (I can't recall the names, I am
not at home) I just doubled the numbers to 16xxx and restarted the backend.
Problem solved for me.

Hope it helps,

Jason
