[mythtv-users] Hang ups after Changing from RecordingOnly to None

I had a similar problem.  Check to see if IVTV is giving you errors
like "DMA_IRQ_ERROR" or something like that.  Also, does it only occur
while you're recording AND using the network? (I noticed that your IRQ
is shared between your capture/network cards).

Try moving your capture card to another PCI slot to make sure it gets
its own IRQ (lspci -v).

Good luck.
