Are you using the cx18, mxl5005s and s5h1409 drivers that came with your distribution or the latest v4l-dvb repository drivers? If not the latest, you should try those first. See the cx18 page on ivtvdriver.org for instructions on getting the latest drivers. http://www.ivtvdriver.org/index.php/Cx18 > I use the following command to scan for channels (on mythbuntu 9.04): > > scan /usr/share/dvb/atsc/us-ATSC-center-frequencies-8VSB > > It manages to find every single channel except for WFFF-TV (aka FOX44).

How does WFFF's analog station look on UHF channel 44? Any snow, ghosting, or interference lines? If so, that indicates poor reception from that transmitter. If so, also please review: http://www.ivtvdriver.org/index.php/Howto:Improve_signal_quality > Is there something I can do help the scan program > find this channel? Well, if it helps, the center freq for an ATSC-8VSB channel on UHF channel 43 is 647.028615 MHz. Maybe you could make up a manual entry in channels.conf, azap to it, and then use femon or dvbtraffic to see if you can get a lock and see the PIDs in use. Where I'm at, PIDs 0x31 (49) and 0x34 (52) are usually in use for the primary video and audio program. > I noticed that it's one of the few (or only) channel that > broadcasts in 720p instead of 1080i, but I doubt that makes much of a > difference... It shouldn't make a difference.
