My experience was that it would usually lock up the video stream with a 
constant barrage of 'prebuffering' errors on the console, but I could 
escape back, and then start live tv again, and it would usually start 
working, with a 'prebuffer' error every 15 seconds or so (with the 
corresponding hiccups). Occasionally, the second time going into watch 
live tv with hard lock the whole box and require a reboot. This got 
preogressively worse, so I switched to no XvMC and have not had any 
problems since (aside from when the ringbuffer fills the HD...) I don't 
have any way of measuring my cable signal to determine if that is a 
problem...
