 I have the previously analog channels 2-77 now broadcast as unencrypted
 QAM channels.[[BR]]

 When I scan for the channels sometimes it correctly finds the 11
 subchannels and sometimes it finds "QAM-256 Channel 78 -- Timed out, 77
 possible channels"  When this happens I get duplicate errors and usually
 have to delete the card and try setup again.[[BR]]

 The cable company is doing something so the old channel numbers are
 remapped on my QAM tv correctly.  For example COMEDY was analog 64 and now
 is found by hdhomerun as Channel 86 Program 64.  On my TV it just appears
 as (digital) 64 similar to how ATSC remaps.
 [[BR]]
 I feel there is something in the way they are remapping that confuses the
 scanner.  My hdhomerun and TV both always find the correct channels.  I
 also attached an hdhomerun scan filtered to unencrypted channels.

 The scan log is from newly install mythbuntu auto-build from 1/27.
