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.
