FYI...
Not sure if that has any affect on IceTV since the LCN's are not changing, just the video format.
10 BOLD recently updated; effective 23rd September, to a High Definition MPEG4 channel with surround sound audio in capital cities around Australia. Channel 10 has also opted not to provide a duplicate SD Mpeg2 version of 10 Bold.
I understand Ten did NOT make any announcements before the change.
