Profiles are only used for mpeg encoding, so the PVR series of cards
use them, but straight digital sources like firewire and HDTV streams
are just copied mpeg streams. It sounds like your trying to playback
an HDTV stream? I don't know why the frontends are segfaulting though,
that sounds like it could be another issue.
