[mythtv-users] Problems tuning DVB-T UK with new BBCA 8k multiplex

[Dave Just]

I wonder if someone can help me with this...  I'm in Edinburgh, Craigkelly 
transmitter which started DSO on Wed so I've had to retune.  As usual the Myth 
"Full Scan" returns a whole lot of confusion because I can receive signals from 
several transmitters (so I get queried for several dozen conflicts, etc, with no 

information about which transport they were found on, the UI displays messages 
with meaningless DB transport index numbers while it tunes, etc).  

Anyway, MythTV old hands know the cleanest way seems is to enter the transports 
manually and tune only on those.  I used info here:

http://www.ukfree.tv/txdetail.php?a=NT233872&irt=593775

All work perfectly except the new BBCA on 522MHz which I cannot get to tune 
properly in MythTV.  The scanner picks up all the channels, but the Myth tuner 
sits blankly on

Signal 90% | BE 0 | (TLMs) Partial Lock

indefinitely.  The final lowercase s never goes to uppercase (I have no idea 
what this means).

VLC, however, can tune to all of the channels on this multiplex without 
problems, I 

just need to  enter 522MHz frequency, 8MHz bandwidth, and all the BBC radio 
and TV stations play perfectly. 

Has anyone else managed to persuade Myth to work with this transport?

I've played with the transport parameters, deleting all channels and rescanning 
for them.  dvb-utils scan returns channels like this:

BBC ONE 
Scot:522000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_AUTO:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_32:HIERARCHY_NONE:101:102:4220


so I set correspondingly in Myth Transport options (I've also tried variations 
of AUTO in the fields).

I'm running Mythbuntu with 0.24 fixes and I have USB Afatech 9015 based sticks.  


I tried playing with some of the card parameters, such as tuning delays, waiting 


for SEQ, etc, but none of these seem to bring me luck.

Any suggestions gratefully received...
