It is quite important that you use dma accelerated tv out. Especially with xawtv as it doesn't do postprocessing this should work until you saturise your pci bus. The freezing thing however suggests that dma is not enabled for your harddisk which is an even bigger performance issue. Make sure you have the right drivers in your kernel, or loaded as module.
