Thanks, I thought it might be hard to straighten the number out on what I
had, so I used timeshift to restore back to just before I built mythtv the
first time and this time I built using cmake and got the right
numbering MythTV Version : v35-Pre-784-g665b315a3b

So now I just need to restore the database etc. All the recordings are on a
separate drive.
