Comment(by Nick Morrott <knowledgejunkie (at) gmail (dot) com>):

 During some testing of the current channel scanner in trunk for UK DVB-T,
 I could not reproduce this issue.

 The bandwidth entries for multiplexes found via individual tuned scans
 were set to 'a', rather than '8' (although note the 'Unsupported bandwidth
 parameter' message during tuning. The one multiplex found during a Full
 Scan for the UK had its bandwidth value set to 8.

 A subsequent tuned scan on anexisting multiplex entry having bandwidth set
 to 'a' did not have any issues detecting the mutliplex and programs
 carried on it (see log below). Tuning to a channel on the multiplex within
 LiveTV was also successful.
