I have eventually come too the conclusion that mythtv is a very hit and miss affair... ie not a exact science

After spending hours, days, months of time, one minute it works next it doesn't, you spend more time (trying) setting up the system than actually watching\listening your media...

Still, I do appreciate the time people have spent on this project
and good luck..

For me well back to xbmc , tvheadend and a look at vdr .....
