[linux-dvb] Malvern UK transmitter

[Simon Kilvington <s.kilvington@eris.qinetiq.com>]

Hi,

	this may be perfectly normal, but I thought it was a bit odd...
I'm receiving DVB-T from the Malvern transmitter, and the frequencies
I tune in to correspond to the ones listed on the OfCom web site:

http://www.ofcom.org.uk/static/reception_advice/digital_trans_guide/show_transmitter.asp-siteID=49.html

but when I run "scan" from the linux-dvb-apps-1.1.0 tar ball - giving
it "T 722166667 8MHz 3/4 3/4 QAM16 2k 1/32 NONE" as a starting point,
it gives the Network Name as Sutton Coldfield. Also, even if I leave
scan running for about an hour it keeps trying to tune into a bunch of
non-existant frequencies (aswell as 5 of the 6 on the Malvern
transmitter) and never tries to tune to the last Malvern frequency
(718MHz) - so it never ends...

	got any ideas?

PS: mythtv and dvbstream seem to cope with me using AUTO for all the
parameters except the bandwidth and the hierarchy, so this file will
get all the Malvern frequencies if you don't care about getting the
QAM etc stuff correct:

dvb-t/uk-Malvern
# Malvern, Midlands
# T freq bw fec_hi fec_lo mod transmission-mode guard-interval hierarchy
T 722166667 8MHz AUTO AUTO AUTO AUTO AUTO NONE
T 618000000 8MHz AUTO AUTO AUTO AUTO AUTO NONE
T 658000000 8MHz AUTO AUTO AUTO AUTO AUTO NONE
T 634000000 8MHz AUTO AUTO AUTO AUTO AUTO NONE
T 682000000 8MHz AUTO AUTO AUTO AUTO AUTO NONE
T 714000000 8MHz AUTO AUTO AUTO AUTO AUTO NONE

here are the params I know:
T 722166667 8MHz 3/4 3/4 QAM16 2k 1/32 NONE
T 618000000 8MHz 2/3 1/2 QAM64 2k 1/32 NONE
T 658000000 8MHz 3/4 3/4 QAM16 2k 1/32 NONE
T 634000000 8MHz 3/4 3/4 QAM16 2k 1/32 NONE
T 682000000 8MHz 2/3 1/2 QAM64 2k 1/32 NONE
(well, assuming the Sutton Coldfied thing doesn't mean this is all
wrong!)

PPS: anyone got a script to import either scan output or dvbtune
output into mythtv? I've manually typed in about 5 channels so far...
