Why yes, but ... I don't remember seeing any mythtv howto's on merging
old and new data base dumps.
Also, (didn't want to bore you) I have cleaned up the recording rules a
fair bit since the old data base dump (seams a lot of people were just
pressing "record" in the program listings creating multiple rules for
the same shows!).
A friend suggested there might be a way to harvest each orphaned
recording's information from the old data base and use "INSERT" to place
the information into the new data base. It is trivial to create a clean
list of orphaned recording files. What I don't know is how to extract
from the old dump and insert into the new.
