If I'm not mistaken, VBI (Teletext) is not yet (fully) supported on the PVR150. I ran into a simular problem with one of the earlier 3.x releases where capture would just hang the device with VBI enabled. Isaac (MythTV) advised switching off VBI in MythTV and the problem got solved. Maybe the newer releases with partial VBI support result in this type of behaviour.
