Hmm, odd still it's throwing DMA errors like that over and over, something is still not right, but I'll take that verbose message out and see. Can it still capture video and work otherwise even after all that, those dma errors are usually a bad sign, saying the dma engine has a bad link, and basically a pci error transfering it, weird.
