 When CheckChannelPrefix in libs/libmythtv/tv_rec.cpp checks for channels
 using the various spacers ("", "_", "-", "#", ".") it can erroneously find
 channels matching the underscore ("_") as it's a SQL wildcard character.

 I noticed that, for example, when I enter '51' on my remote, it gets
 changes to 5_1 even though I'm using '.' (5.1 for example) in all my
 channel numbers.

 I tried to address this by changing the following line:

 QString qprefix = add_spacer(prefix, spacers[j]);

 ...to:

 QString qprefix = add_spacer(prefix, spacers[j] == "_" ? "\\_" :
 spacers[j]);

 ...to force the underscore to be escaped.  This stopped it from adding the
 underscore separator, but for some reason, did not get it to use the '.'
 separator.  I can't figure out why not, as it appears the SQL would find
 channels usging (for example) LIKE '5.%'.
