Changing the name field for a channel does not cause problems. The
callsign is the one used to match recording rules, so changing that
will make all the recording rules fail, unless you update the matching
station field in the record table, and also any custom SQL in custom
rules. That SQL is stored in the description field in rules that are
custom types, but I do not remember what the type field values are for
the custom type rules. The chanid in recording rules does not seem to
be used for much, but I have never delved into the code to check on
