>FYI - Somebody might need to know why I'm doing this.  The reason is that I'm feeding two TVs off of one head.  One TV apparently can't handle the AC3/DTS signal, but the other can.  The one apparently can only handle stereo over SPDIF(actually over HDMI).  Bummer.  It's a Sony Bravia LCD. Would have been nice to know before purchase.

Hi, does your script stop MythTv and restart Mythtv after the database change? I think this is requried when you make this change manually through the setup screens.
 
I need to achieve a similar result with my front end, any chance you could send me a copy of your script.
