The issue he's having isn't doing scanning. It's that a station, which was properly set up once, suddenly won't record because it stopped sending TVCT. They *are* sending PAT/PMT but their PSIP generator has stopped inserting any PSIP whatsoever. This is a problem that needs to be fixed at the station, but is typical of the teething pains we're seeing now (as you know). I think current DVB would be more immune to this problem than current v4l because you do some caching and don't necessarily need the TVCT. -Doug
