OK, it sounds like you need the more-detailed answer than the "generally 
not used" I mentioned before.  With 0.25+, seriesid may be used in 
non-custom recording rules, as explained at 
https://github.com/MythTV/mythtv/commit/02f646ac .  (And thanks to David 
Engel for looking up the commit.)

So, changing seriesid to have different values for different showings of 
the same series would actually break things for some users.

Can you use programid directly, rather than embedding it in the 
seriesid, to tell the 2 episodes apart?
