Apologies for following up on myself but I've been trying with this
and still not getting the default authority populated.  I emptied
and eitcache.  Did a scan with mythtv-setup -v
channel,channelscan,siparser.  Most of the output does not mean that
much to me but I see default authority descriptors mentioned:

2009-10-24 00:36:21.825 ChannelScanSM(/dev/dvb/adapter0/frontend0):
Got a Service Description Table for Channel 26
SDT: TSID(0x4000) original_network_id(0x233a) services(19)
  Service # 0 SID(0x4180) eit_schd(f) eit_pf(f) encrypted(f)
  Service descriptors length: 25
    ServiceDescriptor: 305 (TV)
    DefaultAuthorityDescriptor: Authority(fp.bbc.co.uk)
  Service # 1 SID(0x41c0) eit_schd(t) eit_pf(t) encrypted(f)
  Service descriptors length: 30
    ServiceDescriptor: BBC FOUR (TV)
    DefaultAuthorityDescriptor: Authority(fp.bbc.co.uk)
  Service # 2 SID(0x4240) eit_schd(t) eit_pf(t) encrypted(f)
  Service descriptors length: 30
    ServiceDescriptor: CBeebies (TV)
    DefaultAuthorityDescriptor: Authority(fp.bbc.co.uk)
  Service # 3 SID(0x4280) eit_schd(t) eit_pf(t) encrypted(f)

However looking in channelscan_channel and channel the default
authority is blank
"2";"1";"0";"1";"0";"BBC FOUR";"BBC

Is there something else I need to clear out first or is there still an
issue here?
