All of which makes it intriguing as to why lurking this list and
mythbuntu forums seems to indicate more and more problems with
scanning channels as time (and releases) goes on.

Everyone says "not me" - but there is something going on, and it
certainly is frustrating to a lot of people.

Dissecting a multivariable problem to find which change in variable
broke what and when is a real difficulty I know, but at some stage it
needs to be sorted. (Which is easy to say...)
