[mythtv-users] DCX3200M and the 6200ch program

[Scot Kreienkamp]

GUID has nothing to do with permissions.  There's an option to the 6200ch
program that allows you to direct channel changes to a GUID instead of the
program looking for a vendor/model.  That vendor/model information has
changed on me twice on TWC even though the physical set top box has never
been changed; I believe the GUID never changes so that will work better.  I
think you can get the GUID from /var/log/messages or (if I remember
correctly) by having 6200ch search. Not sure about that second part
though.  I don't have mine in front of me at the moment to look at it.  Run
6200ch with no options or -h or --help or something like that to get the
options.
