A quick follow up, in case others have similar problems.  After trying various
combinations of kernel versions and ivtv versions, I'm back in business.  So
even though the "cat test" worked, it *seems* it was a ivtv (or kernel) issue.
The versions that I'm using now (and that seem to work fine):


Both of those are masked.  Running a masked ivtv isn't new to me, but I
usually avoid masked kernels.  Oh well... it's recording again!
