Actually, after re-reading your description, the problem is your MythTV 
configuration.  As previously alluded in this thread, there are many 
settings which control whether re-record is allowed when things are 
auto-expired.  You need to configure these properly, then use MythTV 
according to your configuration.

Specifically:

Re-record watched
If enabled, programs that have been marked as watched and are 
Auto-Expired will be re-recorded if they are shown again.

(in (main--not Video) General settings on the Auto-Expire screen) 
defaults to false, which means that if you don't manually delete shows, 
they will be allowed to re-record.  Therefore, if you want to allow 
MythTV to auto-expire shows for you instead of manually deleting those 
shows, you need to enable "Re-record watched," and also ensure you mark 
shows as watched when you finish watching them.

There's another setting:

Automatically mark a recording as watched
If enabled, when you exit near the end of a recording it will be marked 
as watched. The automatic detection is not foolproof, so do not enable 
this setting if you don't want an unwatched recording marked as watched.

(in frontend Video Playback settings) you can use to allow MythTV to 
mark shows as watched for you.

Alternatively, when you finish watching a show and no longer want to 
keep it, Delete it yourself (and don't select, "Delete and allow re-record."
