[mythtv-users] Live TV on second Backend while recording?

[mark at zzo.com]

Did you see this:
http://www.snapstream.com/Support/IRTunerInfo.asp
I downloaded the source files but heck if I can figure out what's
going on - it's changing the channel somehow - guess the 'lpfnPlay'
function is one I'd really like to see but it's not in there...
