...so, wait... does that mean that there would be 2 video devices (say,
/dev/video0 (NTSC/V4L) and /dev/video32 (ATSC)), but that they couldn't
be used simultaneously? That would mean that both devices couldn't be
configured for use in Myth, unless a means was devised to let the
scheduler know that they share a tuner. Or am I not seeing this right?
