Thanks for trying it.

I'm afraid I've never seen any HDHR output.  For me HD implies DVB-T2 
implies h264 implies avoid Project-X.  That's why I wrote Mythpycutter.

mplex will only be used if Project-X has been used.

The new script ought to work  (apart perhaps from a short audio glitch 
at cutpoints) if you can set USEPJX to false on detecting HD  - but 
audio sync will probably move at cutpoints if it's not a robust format 
like a DVB Transport Stream, which self-corrects.
