humax pvr9150 not displaying BBC channels

Okay, not quite IT or webdev related but...

Humax PVR having problems displaying BBC channels, checked cable, aerial position, signal strength (twice), two visits to the roof, set an automatic search on all channels, switched off, switched on, rescan, still no BBC!

The obvious thing (should be for an IT professional!) - Menu > Installation > Default Setting > (reset?) Yes

and all is now well. Posting this in case it is useful for others after trying to find a fix on the web.

php displaying question mark icon

found that odd question mark icons in the display of MySQL database content through PHP was due to the http encoding setting in the HTML header of the page:

Standard entry was:
meta http-equiv="Content-Type" content="text/html; charset=utf-8" /

changed to:
meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /

and, as if by magic...the icons now display correctly (e.g. em dash characters).
