Hi, I've been running ivtv in dom0 for a while and for 2 PVR350's I needed swiotlb=256 to get them to run reliably...
(I stopped running Xen a while ago 'cause I actually wanted to assign the PCI slots with the PVR's to a DomU to isolate them, but in the then-current version of Xen specifically this functionality was broken, so no real reason to continue with Xen...)
