I reported this before on the devel list, but there was no answer.
I am trying to use ivtv on a xen0 kernel.
The module loads, everything works like tuning etc, except that video is stuttery - it is playing for about one second, stops half a second, and then plays again one second.
On a non-Xen kernel, everything is fine.
When loading the ivtv module, the following is reported in /var/log/messages (note the PCI-DMA messages):
