I may have spoke too soon as another problem creeped in.
One tuner ended up recording bad video till I rebooted. I saw this before
with the jiffies but nothing popped up in my logs during my test.
This is before the reboot: (all the other tuners output was OK and this
one was the one that recorded the bad video)

Would that cause the video to go garbled? I am recording 720x480 with
mythtv.
Any ideas where I can go from here? I'm going to test again to see if I
can make it repeat.
Thanks,
Jason
