SAP is "Secondary Audio Program", where you can have a second language
on a seperate audio carrier. So, the primary audio would be English,
secondary in the US is traditionally Spanish. I can see where it'd be
useful in live TV mode, and there's an ivtv control that lets you choose
SAP, but I don't think MythTV does anything like that right now.
So, on second thought SAP probably isn't a volume control thing as much
as it is something else. What that something else is, I'm not sure yet. :)
