[mythtv-users] Installation problems (DVB)

I've been having problems getting mythtv to work with a Fusion HDTV
DVB-T card. I have the kernel driver side working and can use
tzap, dvbstream and mplayer manually to view TV through the card.
I'm using mythtv 0.18 with DVB enabled.

I have been having difficulty getting the channels configured.
I've followed the instructions here:


I am able to add channels manually, or scan automatically where all
the channels I want are found. However, from the above instructions,
it appears that it should be possible to add DVB Pids and IDs, but
this menu doesn't appear on my version of mythtv-setup when adding a
channel. I also can't find the "Channel Options - DVB" menu either.

It also doesn't seem to be adding any entries to the dvb_channel or
dvb_pids mysql tables. I tried adding a row like this to the
dvb_channel table:

REPLACE INTO dvb_channel (chanid, serviceid, networkid, providerid, transportid, frequency, inversion, symbolrate, fec, polarity, satid, modulation, bandwidth, lp_code_rate, transmission_mode, guard_interval, hierarchy, pmtcache) VALUES (1000, 529, NULL, NULL, 1,  205625000, 'a', NULL, '3/4', 'h', 0, 'qam_64', '7', '3/4', '8', '1/16', 'n', NULL);

(this is for ABC Canberra, Australia). the chanid correlates to the line
in the channels table.

I also added a couple of entries like this:

REPLACE INTO dvb_pids (chanid, pid, type, lang) VALUES (1000, 512, 'v', '');
REPLACE INTO dvb_pids (chanid, pid, type, lang) VALUES (1000, 650, 'a', '');

However, I still get these errors when I start mythbackend

without adding the entry to dvb_channel row I don't even get the
"DVB#0 Status: LOCK" message. 

Can someone help me with how to setup the channels or point me to some
up to date documentation? Or even better does anyone have a digital
channel configuration for Canberra?
