I find that on Debian Sid and Fedora Rawhide using the distributed kernels and libdvbv5, dvbv5-scan fails to get activity from the device. PCTV 282e works fine. Fedora Rawhide has kernels 4.4 and 4.5, Debian Sid 4.3. Debian Sid distributes dvb-tools as well as libdvbv5 (1.8.0). Fedora Rawhide only distributed libdvbv5 as far as I can tell, but I compiled dvbv5-scao from source from a git repository clone, but it behaves the same. On Debian Sid with PCTV292e: |> dvbv5-scan /usr/share/dvb/dvb-t/uk-CrystalPalace=C2=A0 Cannot calc frequency shift. Either bandwidth/symbol-rate is unavailable (yet). Scanning frequency #1 490000000 =C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0(0x00) Signal=3D 0.00dBm Scanning frequency #2 514000000 =C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0(0x00) Signal=3D 0.00dBm Scanning frequency #3 570000000 =C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0(0x00) Signal=3D 0.00dBm Scanning frequency #4 506000000 =C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0(0x00) Signal=3D 0.00dBm Scanning frequency #5 482000000 =C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0(0x00) Signal=3D 0.00dBm Scanning frequency #6 529833000 =C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0(0x00) Signal=3D 0.00dBm Scanning frequency #7 545833000 =C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0(0x00) Signal=3D 0.00dBm Swapping to the PCTV 282e, scanning works entirely as expected: if there is a lock it happens immediately and the channels are shown after a while; if there is no immediate lock there is a spinning of the signal strength value =E2=80=93 definitely not just a solid zero. I note that PCTV 282e has a green light on permanently and works fine. PCTV 292e lights up blue when plugged in and then the light goes out. On Linux it never comes on again. Trying the device on Windows with the distributed software the blue light comes on every so often as activity happens. The hypothesis is that the device is not being driven properly. And yet people appear to be using the device? --=20 Russel. =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D Dr Russel Winder t: +44 20 7585 2200 voip: sip:russel.winder@ekiga.n= et 41 Buckmaster Road m: +44 7770 465 077 xmpp: russel@winder.org.uk London SW11 1EN, UK w: www.russel.org.uk skype: russel_winder --=-0JpMxsx+Eb4t41VLeSfy Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iEYEABECAAYFAlakYOwACgkQ+ooS3F10Be8boQCfXUxPuqS/IEGWQSqpmN60BERu HaIAoKrVlHJwkt0Z+LPC9KPogM7dCzTQ =S/hn -----END PGP SIGNATURE----- --=-0JpMxsx+Eb4t41VLeSfy--
