Channel scaning ok, but LiveTV doesn't work

[NarsilAnduril]

Hi guys,

PVR-500 on a mythbuntu 8.04

Channel scanning returns the correct frequencies, but when I try LiveTV, the black screen of death goes back to GUI after a couple of seconds.

I only see snow in MPlayer opening /dev/video0 and /dev/video1
