I've had the same problem with recordings on my x86_64 system.  After
some searching I noticed that my first tuner shared an interrupt with
one of the disks in my raid array.  I thought that this might be
causing some data to get dropped on the capture card during heavy I/O.
 I recently rearranged my PCI cards in an attempt to reorder the
interrupts, and it appears to be fixed.  I can't say for sure that my
diagnosis was correct, but it sounds plausible to me.  Any opinions?
